Features

Elongated valve cover on cryogenic variant to prevent cold conduction and freezing of packing, eliminating adverse impact of ultra-low temperature on stuffing box sealing performance
Main components undergo hardening treatment, ultra-low temperature treatment, and ultra-precision processing for precise flow and pressure regulation
Passed strict ultra-low temperature deep cryogenic tests for stable operation under extreme conditions
Three-way variant (C730) capable of flow combining or flow splitting duty
Customisable for high temperature, high pressure, strong corrosion, high precision, and low-temperature control conditions

Description

A series of customised control valves designed for complex operating conditions including high temperature, high pressure, strong corrosion, high precision, and low-temperature service. The valves provide precise regulation of flow and pressure to meet stringent industrial process requirements. A cryogenic variant (featuring an elongated valve cover and hardened main components) is specifically engineered for ultra-low temperature applications down to -196 °C.

Selection notes

This control valve is a cryogenic, three-way and specialty pattern.

Sizes run DN15 to DN300, in PN16, PN25, PN40, PN63, PN100, PN160, PN250, Class 150, Class 300, Class 600, Class 900, Class 1500.

The body is offered in CF8, CF8M, CF3 and CF3M, so the grade can be matched to the service rather than the other way round.

Stated service media include natural gas, air separation products, liquid nitrogen, petroleum and chemical industry fluids.

Working temperature is -196°C to -100°C.

Linear Series configurations

View full Linear Series system →

This product is part of the Linear Series modular system. All configurations share the same hydraulically operated body: the control function is set by the pilot valve(s) attached. An existing Linear Series body in the field can be reconfigured for a different duty simply by swapping the pilot, without replacing the body.
