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.
Normal positions before startup are with the main valve and electric pilot closed, pressure pilot open, and temperature pilot open.
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.
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.
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.
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.
Installation and Maintenance Instructions
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.
The DC Series are type diaphragm pneumatic actuators are used to operate linear displacement valves in modulating or block control systems.
