Features and Benefits

Automatic relief of thermal body Pressure-upstream, Double block and bleed capability.

1.With valve closed the seal(A) is initially established by raised PTFE ring on seatfaces.

2.Upstream pressure forces gate against the PTFE ring on the downstream seat. A double seal is established:PTFE-to-metal and meat-to-metal O-ring(B) avoid any down-stream flow.

3.Bleeding body pressure the upstream seal is activated by upstream line pressure.A double seal is established:PTFE-to-metal and metal-to-metal.O-ring(B) avoid any down-stream flow.

4.Upstream seal automatically relieves excessive body pressure a used by thermal expansion.

Here are some key advantages of Through Conduit Gate Valves:

1. Bi-directional flow capability: Through Conduit Gate Valves are designed to allow fluid or gas flow in both directions. This bidirectional feature enhances flexibility and allows for easy installation in systems where the flow direction may change.

2. Reliable sealing: Through Conduit Gate Valves typically employ metal-to-metal seating, which provides a tight and reliable seal even in high-pressure or high-temperature applications. The metal seats can withstand harsh conditions and maintain their sealing integrity over an extended period.

3. Minimal pressure drop: The streamlined flow path of Through Conduit Gate Valves, coupled with their full-bore design, results in minimal pressure drop across the valve. This characteristic ensures optimal flow rates, energy efficiency, and system performance.
