1 / 2Truevalve pneumatic piston valve with threaded pipe ends and angle-pattern body.
Threaded Pneumatic Piston Valve
Threaded process valve with spring return
The threaded pneumatic piston valve is intended for automatic on/off service in threaded pipework. Air opens the angle-pattern valve; the spring returns it to its closed position when air is removed. For a replacement, check the pipe thread and the space available above the actuator together.
Final selection requires the complete product code and the service conditions.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Automatic shutoff in water, air or steam lines after service verification · Cyclic on/off operation in machinery and process units
Selection considerations
Specify process differential pressure separately from available control air pressure.
Specify the nominal line size and connection standard, together with the need for isolation, regulation or automation. Two valves of the same nominal size may differ in materials or connection dimensions.

Frequently asked questions
Does the nominal thread size identify the valve?+
Not by itself. Specify thread standard, body length, flow, line pressure, temperature and minimum available pilot air pressure.
Are pilot air pressure and process pressure the same?+
No. Pilot air drives the actuator, while process pressure is the pressure of fluid in the valve body. Report both separately, along with the differential pressure on closure.
What should I verify before specifying Truevalve Threaded Pneumatic Piston Valve?+
Evaluate pressure and temperature together. Verify the ratings that apply to the selected body, sealing materials and end connections in the model-specific technical document.
What should I include in my quotation request?+
Line size and connection standard; Fluid, operating pressure and temperature; Isolation or control duty and actuation method. For replacement equipment, also provide the nameplate and connection dimensions.
Where can I check the technical drawing and dimensions?+
Open the manufacturer PDF in the Technical Documents section. Match the relevant entry to the product type, nominal size and variant code. Not every option in a family catalogue belongs to the same product.
