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.

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.

Stonel Position Transmitter
The Stonel Limit Switch is for use with the K Series pneumatic control valves and PN5000/6000 actuators. It is mounted on the PN5000/6000 actuators and can provide visual indication if the valve is fully open, fully closed, partially open (0-100%) or partially closed (0-100%). By comparing flow rates over time with your valve position, you can determine valve wear.

Cast Iron Float and Thermostatic Steam Traps FTB Super Capacity Series
The trap contains a float valve mechanism which modulates to discharge condensate continuously at steam temperature. Noncondensible gases are released by a separate internal balanced pressure thermostatic air vent.

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.
