ChemValve has an innovative design for your double block and bleed needs. You will get all the advantages of the model 790EB Fully Lined Plug Valve but suitable for true double block and bleed requirements for isolation.
The ChemValve design reduces the need for two valves and a bleed valve to one valve and a bleed valve. Our double block and bleed valve has an upstream seat and a downstream seat. Then a bleed pipe runs down from the middle of the valve to insure isolation. This substantially reduces the cost by eliminating extra valves and spool pieces. Also, we eliminate potential emissions and leak paths associated with multiple flange connections.
Since 1987, ChemValve has manufactured fully lined plug and ball check valves. In 1993, Albert H. Klopfenstein took ownership and began innovating design solutions for challenging flow applications. As a result, ChemValve established a reputation in the field for providing longer lasting and high performance fully lined plug and ball check valves. ChemValve’s commitment to engineering innovation allows it to meet a variety of customer specifications upon request.
