PP Valve are mainly used in aggressive medium of oil,Chemical,food,and pharmaceutical industries,such as hydrochloric,vitriolic,and alkali solutions,with pressure and vacuum relief. Weight loaded. Pressure setting:2.0kPa- 6.9kPa,Vacuum...

Series8140 are used when vacuum relief is the only requirement. Intake relief necessary under working conditions is achived by a spring or weight loaded pallet. The type 8145and 8147 may be side mounted on the tank body or piped in.. Features Designed and tested according to API2000； Vertical/Horizontal installation; Size 2” through...

Material:CS SS. Size:1”----16”. Flange Class:600Lb---2500Lb.   Vibration guide structures at top and bottom of flow-sensing disc provide full support to assembly.Top guide includes a snubber to minimize vibration. Built-in Check Valve Spring-loaded against seat,the flow-sensing disc acts as a main flow check valve. Bypass...

Series 9900 can work at-196c conditions, and have been already used in petroleum, natural gas transfers and air-separating industries, providing effective protection for the tanks which stores ultra-low temperature materials. Features Designed and tested according to API2000； Size 2” through 12”； Pilot control keeps high seats...

The 9800 Series Pilot Operated Valve have two principal advantages over other types of relief valve：It is bubble tight to set pressure.And,the full flow folw is attained at no more than 10% over-pressure.These characteristics permit an operating pressure nearer to the maximum allowable woking pressure of the tank.High operationg pressures reduce...
