Spira-trol Quick Ship Program

The Spirax Sarco Spira-trol™ control valve Quick Ship program has been designed to allow the control valve to be readily configured, built and shipped within 4 days or less

LSB31, LSB32, LSB33, LSB34, LSB71, LSB72, LSB73 and LSB74 Limit Switch Boxes for BVA300 Series Actuators

LSB limit switch boxes are normally used for indicating valve open or valve closed position. They also allow switching points to be adjustable over the full range of actuators.

Stainless Steel Direct Operated Pressure Regulator SRV2

The SRV2S is a compact, stainless steel, direct acting pressure reducing valve for steam or gases such as compressed air. All wetted parts are constructed in 316L stainless steel.

PP Series Pneumatic Series Actuator

PP Series is a linear pneumatic piston type actuator that provides positive throttling or on-off operation for automatic control valves. The cylinders are designed for instrument air supply pressures of up to. 100 psi. This actuator can be single or double-acting and spring-return. This actuator is fully fi eld reversible for air-to-open or air-to-close action.

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.
