Fushiman All fluids AWR type back pressure valve

Model	Nominal diameter	Primary measurement pressure range	Maximum operating temperature	Body Material	Connection
AWR	15–50	0.03～2.0MPa	220℃	FC,, SCPH, SCS	Flanges

Simple structure, direct-acting back pressure valve.
Fewer failures and long lifespan.
When the diaphragm material is stainless steel, it is compatible with steam, gas, water, and liquids.

Note (¹): If the diaphragm is made of synthetic rubber, the set pressure should be 1.0 MPa or lower.
(²): For temperatures exceeding 60°C and up to 110°C, manufacturing is also available.

Remarks:

ASME Class 150・300 can also be manufactured.
Manufacturing with a stainless steel valve body is also available.
