Large diaphragm; more stable reduced pressure regulation with external impulse tube.
The Cv value is high, so the flow capacity and control ability are greatly improved; one or two sizes smaller than nominal can be used.
Spherical main valve provides good sealing and reduced leakage and valve seat (ANSI Class IV).
Low pressure pressure control (0.02 MPa or less) is possible.

Connection		EN PN 25/40

Pilot diaphragm valve control with high-precision low pressure regulation. This option is optimal if pressure surges significantly affect quality.

* 1. Standard external impulse tube. When installing a pressure relief valve, be sure to attach the supplied impulse pipe and compensator. If the impulse line is not connected, the valve will not work. (Available with internal impulse pipe (nominal diameter: 15 A to 10 A) in different specifications. Note that the Cv value in the pipe in the inner impulse pipe is lower than in the external impulse pipe.)

- Remote pilot options available. & nbsp;

- ASME flange options available.

Manual Set Point Type Remote Control (Maximum distance of 5 meters)
