"NEW ITEM" LAUNCHED
- "CLA-VAL" SERIES 650 Pressure Relief / Safety Valve

650-01.jpg
650-33.jpg

Model: 650-01
(Normally Close)

Model: 650-33
(Normally Open)

Cla-Val 650 Series Pressure Relief/Safety Valves are pressure actuated through a pilot control system. Operation is fully automatic, and pressure settings can be easily changed. The valve can be used as a pressure relief valve, pressure sustaining valve, back pressure valve, or safety shut-off valve.


When upstream pressure rises above an acceptable level:-

(A) The Model 650-01 is assembled as a normally closed valve that opens quickly to maintain steady line pressure.

(B) The Model 650-33 is assembled as a normally open valve that closes quickly to protect downstream piping.

  • Typical Applications - 650-01

Pressure Relief Service


This fast opening, slow closing relief valve provides system protection against high pressure surges on pump start up and pump shut down by dissipating the excess pressure to a safe location.

  • Typical Applications - 650-33

Safety Shut-Off Service

​

When the 690-01 PRV discharge pressure is as set, the 650-33 safety valve is fully open. When the PRV outlet
pressure rises above normal, the 650-33 valve will begin close to isolate the excess pressure from the downstream piping. Operation is completely automatic and may be easily field adjusted.

​Operation and Installation:

The Cal-VAL AQUA 90-501 strainer is used when effective filtration is required. Of compact design, maintenance is fast and easy strainer mesh perpendicular to flow optimizes pressure drop. Moreover, the AQUA 90-501 strainer model can be equipped with an autonomous programmable flushing valve ( CLA-VAL SERIES ECO) allowing fast flushing without removing the top cover. The strainer may be installed in any position, however installation with the cover on top side is recommended.
