Select diaphragm/packing, adjustment range, connection, mounting and material compatibility.
Application & RFQ details
Match chemical compatibility, pump delivery at back pressure and suction conditions. A process back-pressure valve is not a certified pressure-vessel safety valve.
Standards & documents
Require product-specific pressure-temperature limits, wetted-material compatibility and functional tests. Applicable pressure-equipment requirements are order-specific.
Packing
Individual braced cartons/crates; drain and seal wetted passages; ship dampeners depressurized.
