Note

Note

 N/A Plugs and bleed plugs are available and can be ordered separately.

Please note that the standard o-ring in all the NOSHOK valves is FKM and the standard handles are "T" handles (HL2).

The handle material will always match the material of the valve, unless otherwise specified. For example, the "T" handle (HL2) on the 204-MFC will be steel. When only the standard configuration is needed, no additional designations are necessary. Please consult the factory for special application requests

All NOSHOK valve products conform to the MSS SP-99 instrument valves standards, and valves supplied with packing also conform to MSS SP-132 compression packing systems for instrument valves standard.

Other o-ring materials available on request.
