Control Valves

Spirax Sarco's state-of-the-art control valves are available to suit almost every application. Designed to provide accurate, repeatable performance with the utmost reliability.

A compact range of linear pneumatic actuators that are a perfect match for our line of globe control valves. An extensive range of sizes and spring ranges to suit valve shut-off requirements and process needs are available.

Using the same valve range as the linear pneumatic actuators, electric actuators provide an alternative solution to applications that require an electrical powersupply. A comprehensive range of accessories are available.

To complement the range of pneumatically actuated control valves, the pneumatic and electropneumatic positioners will allow small actuators to close against higher differential pressures, eliminate hysteresis and improves accuracy and positioning time. Variants are available with automatic commissioning, smart control, programmable functions and digital communications.

Choose from a comprehensive range which offers a choice of body design, materials, connections, seals and options, plus specialty valves which are suitable for specific applications and different process media.

A comprehensive range of actuators provides cost effective selection. Smaller actuators are required because of low torque valves. Actuators can operate with compressed air between 45 psig (3 barg) and 90 psig (6 barg). Electric actuators are also available.

For pressure or temperature control, controllers are available with simple proportional control action, or with the addition of integral action. Temperature sensing is via a nitrogen filled direct expansion system and pressure sensing by interconnecting pipework to an internal bourdon tube.

The Spirax Sarco range of piston actuated valves provide a competitive solution for on/off control applications by combining many key benefits in one valve.

It is a solenoid valve equipped with an adjustable timer that controls the 'ON' time and 'OFF' time allowing a flexible control of a condensate draining process. The ADV is typically used to remove pressurized condensate from an accumulator tank or any vessel, which requires draining. The ADV allows the process to be done both automatically and economically.
