Industry Applications

How to specify a hygienic valve for food and beverage lines: CIP and SIP conditions, Ra surface finish, the dead leg rule, 316L bodies, EPDM, FKM and silicone temperature limits, and clamp versus welded connections.

Valve selection on chiller and fan coil circuits: the size threshold for butterfly valves, manual balancing versus PICV, low delta-T syndrome, on/off against modulating control, and condensation and insulation.

Which valve works on screening, pumping, sludge and return activated sludge lines? Knife gate versus butterfly, rag binding, abrasion, elastomer choice, actuator ingress protection and service intervals.

Knife gate valves are the standard for sludge, slurry and solids-laden fluids. Where they are used in wastewater and mining plants, and how to select materials and actuators.

Valve selection for fire protection lines is a discipline of its own: UL listed and FM approved products, indicating valves with tamper switches, alarm check valves and NFPA 25 testing.
