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.

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.

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.

STS17.2 Stainless Steel Compact Pipeline Connector Steam Trapping Station

The STS17.2 compact pipeline connector steam trapping station has been designed to provide a convenient ready to install trapping solution, which includes: upstream and downstream isolation valves, body incorporating quickfit connector + strainer and check valve blanking plug.

Combination Pilot Operated Regulators Types 25PT, 25PE, 25TE, 25PTE, 26PT, 26PE, 26TE, and 26PTE

Normal positions before startup are with the main valve and electric pilot closed, pressure pilot open, and temperature pilot open.

SA121, SA122, SA128 and SA1219 Self-acting Temperature Control Systems

A range of self-powered control systems that incorporate sensor, actuator, set point adjustment / indicator for use with 2- port and 3-port control valves.
