Vacuum Check Valves - Series 3000

Minimum Pressure Drop | Full Flow | Stainless Steel Trim

Size/Attachment/Body Type Chart:

Seal Type:

Pokorney Vacuum Check Valves are designed and engineered for the unique problems of the vacuum field. Featuring extremely low pressure drop, they open on less that 1/10" W.C. Special design permits light-weight stamped stainless steel disc to open fully, providing full flow with minimum resistance. Non-scuffing disc mechanism has free action at all times. Positive shut-off even at minimum flow is assured by unique elastomeric permanently molding facing (Viton or Ethylene Propylene - EPDM, or Teflon) on specially designed stainless steel disc. Noiseless, ruggedly constructed Pokorney Vacuum Valves have a high safety factor. Each valve is individually tested before shipment over a range from 0 to 50 p.s.i. back pressure and must show ZERO leakage at ALL pressures. Precision manufactured throughout. All internal trim stainless steel. Guaranteed pip concentricity.
