Pilot Controlled Check Valve (PVG/PVT/PVTF)

PVG/PVT/PVTF

Pilot Controlled Check Valve (PVG/PVT/PVTF)

Feature:

1.These check valves allow flow in one direction and prevent flow in the reverse direction, until operated by pilot pressure to allow free reverse flow.

2.The specified cracking pressure is required to open the valve to allow free flow direction.

Operation of internal and external drain types

Internal Drain (Fig. A): When the outlet side P1 is directly connected to the tank in reversed free flow (Fig. A), the internal drain type is normally used.

External Drain (Fig. B): When the back pressure is applied to the outlet side P1 (Fig. b), be sure to use the external drain type.
