Pop-Type Relief Valve

Model No. NSV-30_

Allows you to set various relief pressures.
The steel ball opens the valve seat and the valve fully opens at once.
You can manually exhaust air.
Can be directly screwed in without using nipples.
Compact with a small footprint

S_	Set to the specified pressure.*
F_	Set to the specified pressure.*

*The products can also be delivered with the specified pressure preset.

・When presetting the specified pressure in the resettable state, add S to the end of the standard Model No. and enter the set pressure after that.

・When presetting the specified pressure in the unresettable state, add F to the end of the standard Model No. and enter the set pressure after that.
(Example) Model No. NSV-30_ F4.0 when using the product in the unresettable state with the relief pressure set to 0.4 MPa
