Features and advantages

TWT series is the direct piston type pressure reducing valve. By adjusting the spring pressure to set the outlet pressure, the use of the diaphragm sensor outlet pressure changes, the opening and closing of the piston to adjust the main valve throttle area over the size of the valve, to achieve decompression function.

The utility model has the advantages of improving the sensing efficiency of the pressure change of the outlet pressure and improving the sensitivity, and greatly reduces the pressure deviation caused by the change of the upstream pressure and the flow rate. The machined bronze body makes the seat parts longer.
