This page explains how Isolation/Control Valves is classified within Machinery and Equipment Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
Isolation/Control valves are critical components of purge manifolds that serve dual functions: isolation valves completely shut off fluid flow for maintenance or safety purposes, while control valves precisely regulate flow rates, pressure, or direction during purge operations.

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Isolation valves are designed to completely shut off fluid flow for maintenance or safety, providing a tight seal when closed. Control valves modulate flow to regulate rate, pressure, or direction during purge operations, using actuators to adjust valve position based on controller signals.
The body material is stainless steel CF8M (ASTM A351), and the seat material is PTFE (ASTM D4894). These materials provide corrosion resistance and chemical compatibility, but the PTFE seat limits the operating temperature range to -40 to 85 °C.
The operating temperature range is -40 to 85 °C, limited by the seat material at extremes.
Relevant standards include ISO 6708 for nominal diameter, ISO 5208 for pressure and leakage rate, IEC 60381 for control signal, IEC 60038 for supply voltage, and IEC 60529 for enclosure rating. Material standards include ASTM A351 for body and ASTM D4894 for seat. Always verify compliance with the manufacturer.
