Ideal Vacuum Delta-P Anti-Suckback System Protection Valve with NW KF-16 Flanges, 110VAC, 60 Hz Solenoid. The Delta-P Valve (DPV) is an important component of any rough or high vacuum system. The DPV provides anti-suckback and vacuum system isolation from the mechanical backing pump during a power outage. It prevents backstreaming and the migration of contaminants (e.g., rotary pump oil or scroll pump tip seal particles) into the vacuum system. It also protects a high vacuum pump from damage. FEATURES: Preserves chamber vacuum pressure during power outages Closes automatically (approx. 25 ms) upon power interruption Automatically re-opens when vacuum is restored Requires no additional power source or gasses to operate Operates on differential pressure between ambient atmosphere and roughing pump’s vacuum level Isolates high vacuum pump and/or vacuum chamber system from mechanical pump Prevents backstreaming and migration of oil or particulate contaminants into the vacuum system Mounts directly on the inlet side of the mechanical roughing pump Compact design - 3-inches in diameter and 4-1/4” in length (5” with KF50 flange ends) Works in any orientation: vertical, horizontal, or inverted Four available flange connection sizes: KF16, KF25, KF40, and KF50 Non-restrictive flow for flange sizes smaller than KF-50 Three solenoid voltage options: 110VAC, 220VAC, or 24VDC Constructed entirely of vacuum compatible materials in the U.S.A. Mean Time Between Failure (MTBF) rating of more than 10,000 cycles Every valve is leak tested to 1x10-9 atm cc/sec Helium before delivery Use with clean, dry, air or inert gases. The Delta-P Valve operates on the Differential (Delta) Pressure (P) between ambient atmosphere and the roughing/backing pump’s vacuum level. During a power failure, the mechanical pump is vented to atmosphere from its inlet flange which pushes debris towards the mechanical pump. This stops undesirable material from being swept into the system when the pump restarts. The DPV is a compact, inline unit which mounts directly on the inlet flange of the mechanical pump. It is available with either KF-16, KF-25, KF-40, or KF-50 vacuum flanges, and solenoid voltages of 120 VAC, 220 VAC or 24 VDC. The DPV can be supplied in a custom configuration with different flanges on either end for no additional cost (please inquire). DPV closure speed is approximately 25 ms, faster than other isolation valves. This is due to the reduced moving mass of our advanced piston design. Flow is unrestricted with flange sizes smaller than KF-50. A slight reduction in conductance may be experienced with pumps that have a high pumping speed and KF-50 inlet flange. The DPV can be mounted in any orientation; vertical, horizontal, or inverted. All parts that make up the DPV have been carefully selected for vacuum system compatibility and longevity. To ensure the Delta-P Valve you receive is of the highest quality, all production and assembly is done in our own manufacturing facility in Albuquerque, NM, U.S.A. Furthermore, every Delta-P Valve is helium leak tested and must meet our stringent quality control standards before it leaves our facility. Upon delivery, your Delta-P Valve is ready for immediate installation into a new or existing system. The Delta-P Valve is intended for use with clean, dry air or inert gases. For processes that use or create corrosive or toxic gasses, the valve’s solenoid breather vent must be replaced with an exhaust line that exits to the facility exhaust.

Ideal Vacuum Delta-P Anti-Suckback System Protection Valve with NW KF-40 Flanges, 24VDC SolenoidThe Delta-P Valve (DPV) is an important component of any rough or high vacuum system. The DPV provides anti-suckback and vacuum system isolation from the mechanical backing pump during a power outage. It prevents backstreaming and the migration of contaminants (e.g., rotary pump oil or scroll pump tip seal particles) into the vacuum system. It also protects a high vacuum pump from damage. FEATURES: Preserves chamber vacuum pressure during power outages Closes automatically (approx. 25 ms) upon power interruption Automatically re-opens when vacuum is restored Requires no additional power source or gasses to operate Operates on differential pressure between ambient atmosphere and roughing pump’s vacuum level Isolates high vacuum pump and/or vacuum chamber system from mechanical pump Prevents backstreaming and migration of oil or particulate contaminants into the vacuum system Mounts directly on the inlet side of the mechanical roughing pump Compact design - 3-inches in diameter and 4-1/4” in length (5” with KF50 flange ends) Works in any orientation: vertical, horizontal, or inverted Four available flange connection sizes: KF16, KF25, KF40, and KF50 Non-restrictive flow for flange sizes smaller than KF-50 Three solenoid voltage options: 110VAC, 220VAC, or 24VDC Constructed entirely of vacuum compatible materials in the U.S.A. Mean Time Between Failure (MTBF) rating of more than 10,000 cycles Every valve is leak tested to 1x10-9 atm cc/sec Helium before delivery Use with clean, dry, air or inert gases. The Delta-P Valve operates on the Differential (Delta) Pressure (P) between ambient atmosphere and the roughing/backing pump’s vacuum level. During a power failure, the mechanical pump is vented to atmosphere from its inlet flange which pushes debris towards the mechanical pump. This stops undesirable material from being swept into the system when the pump restarts. The DPV is a compact, inline unit which mounts directly on the inlet flange of the mechanical pump. It is available with either KF-16, KF-25, KF-40, or KF-50 vacuum flanges, and solenoid voltages of 120 VAC, 220 VAC or 24 VDC. The DPV can be supplied in a custom configuration with different flanges on either end for no additional cost (please inquire). DPV closure speed is approximately 25 ms, faster than other isolation valves. This is due to the reduced moving mass of our advanced piston design. Flow is unrestricted with flange sizes smaller than KF-50. A slight reduction in conductance may be experienced with pumps that have a high pumping speed and KF-50 inlet flange. The DPV can be mounted in any orientation; vertical, horizontal, or inverted. All parts that make up the DPV have been carefully selected for vacuum system compatibility and longevity. To ensure the Delta-P Valve you receive is of the highest quality, all production and assembly is done in our own manufacturing facility in Albuquerque, NM, U.S.A. Furthermore, every Delta-P Valve is helium leak tested and must meet our stringent quality control standards before it leaves our facility. Upon delivery, your Delta-P Valve is ready for immediate installation into a new or existing system. The Delta-P Valve is intended for use with clean, dry air or inert gases. For processes that use or create corrosive or toxic gasses, the valve’s solenoid breather vent must be replaced with an exhaust line that exits to the facility exhaust.

O-Ring Seal Replacement Kit, Viton, for all Delta-P System Isolation Protection Valves This O-ring kit replaces all three O-rings in any Ideal Vacuum Delta-P System Isolation Protection Valve. The two larger O-rings replace the flange end seals, the smaller O-ring replaces the actuator cup seal. All three O-rings are made of Viton for maximum vacuum system compatibility. All three O-rings should be replaced if any one of them requires replacement. The flange end O-rings should be lubricated with vacuum grease prior to reassembly of the Valve. The actuator cup O-ring should not be greased. The Delta-P Valve should be tested after O-ring replacement and Valve reassembly to ensure proper function. Instructions and test procedures are discussed in the downloadable Deltas-P User''s Manual here.

O-Ring Removal Tool, Non Scratch Polycarbonate, Keeps O-Ring Seals and Grooves from Damage This O-ring removal tool, made of non scratch, tough polycarbonate plastic, allows you to remove O-rings from the groove without damaging either the O-ring seal or the groove. This 5-1/2" long, nearly unbreakable tool has a prying tip on one end, and a hook on the other which allows you to remove even the most stubborn O-rings, even in hard-to-reach places. This tool is a must have in your toolbox! We recommended it for installation, maintenance and service on the Ideal Vacuum Cube modular chamber system, or with any vacuum component. Note: Color may vary.

Delta-P Valve Maintenance and Service Tool Kit This simple toolkit includes a 7/64 hex key wrench and an O-ring removal tool.
