85 Series

The 85 Series check valve, which is considered a high-quality valve, provides excellent sensitivity, fine control and easy adjustment, with very-reduced weight and size.

Type PF5 and PF6 Piston Actuated Valves

PN1000 and PN2000 Pneumatic Actuators

A range of single spring linear actuators having 5 diaphragm sizes for matching the requirements of different valves at various differential pressures. Each actuator is fitted with a combined mechanical stroke indicator and anti-rotation guard. The actuators are designed for easy conversion from spring extend to spring retract, and vice versa, without the need for special tools.

PN5000 and PN6000 Series Pneumatic Actuators

A range of compact linear actuators having 4 diaphragm sizes for matching the requirements of different valves at various differential pressures. Each actuator is fitted with mechanical stroke indicators and incorporate a rolling diaphragm to give linearity over the full operating stroke.

Acoustic Plates, Diffusers, and Suppressors

Spirax Sarco acoustic plates are designed to be bolted between conventional ANSI class 150 or 300 piped flanges on the downstream side of a regulator or control valve usually between flanged pipe reducers.

Acoustic Silencers

The Spirax Sarco acoustic silencer is designed to attenuate noise generated by control valves and/or pilot operated regulators. The silencers are particularly effective in limiting the propagation of valve generated noise into the downstream piping. Upon flow and piping configuration, noise attenuation of up to 35 dBa can be expected.

Type 25E and 26E Electric Pilot Operated Valve (for Steam or Air Service)

Installation and Maintenance Instructions

SX80 Process Controller

The SX80 controller is a 1/16 DIN panel mounted unit, suitable for single and multiple set point applications utilising the Spirax Sarco range of pneumatic or electric control valves and electrical and electropneumatic instruments.

Air Vent 6A

The 6A Air Vent has both a float and a thermostatic bellows for use where air, condensate and steam may be present (as in one pipe steam heating systems.) The 6A will discharge air, while preventing the escape of either condensate or steam. An outlet check valve prevents the re-entry of air.

BC3200 and BC3210 Blowdown Controllers

The BC3200 and BC3210 are dual voltage controllers which monitor the conductivity of liquids, and are used with a boiler blowdown valve or condensate dump valve to monitor and control TDS levels.
