Product Overview

Industrial Piston Valves for Process Piping

A piston valve is a type of industrial valve in which a piston-like closing element moves through sealing rings to control or isolate flow.

In suitable designs, piston valves are used for shut-off duties involving compatible process fluids and steam. Their performance depends on the valve construction, sealing materials and operating conditions.

Buyers searching for piston valve types should distinguish between piston shut-off valves, piston check valves and piston-operated control valves. These designs serve different purposes.

Working Principle

Understanding Piston Valve Working

A piston shut-off valve operates through the movement of a piston element within a sealing arrangement.

Opening the Valve

The operating mechanism moves the piston away from its closed position to allow flow.

Flow Through the Body

With the valve open, the process medium passes through the available flow passage.

Closing the Valve

The piston moves into the sealing arrangement to provide shut-off according to the valve's design.

Product Features

Key Features of Piston Valves

Piston-Type Closing Element

Uses a piston-style closing arrangement for suitable industrial shut-off duties.

Graphite Sealing

Graphite is listed as the sealing material in both supplied configurations.

Flanged & Screwed Designs

Separate configurations are listed for different piping arrangements.

Industrial Body Materials

ASTM A216 WCB and forged construction are included in the supplied specifications.

Multiple Pressure Classes

The supplied data includes Class 150, 300 and 800, depending on the configuration.

Technical Selection Support

Buyers can enquire with their pressure, temperature, size and connection requirements.

Valve Selection Knowledge

Different Piston Valve Types Explained

Not every valve described as a piston valve performs the same function.

Piston Shut-Off Valve

A piston type valve used for suitable isolation duties. The supplied flanged and screwed specifications relate to this product category.

Piston Type Check Valve

A piston type check valve, also called a piston style check valve, is intended to restrict reverse flow. It is different from a manually operated piston shut-off valve.

Spring-Loaded Piston Check Valve

A piston spring check valve or spring loaded piston check valve uses a spring in its closing mechanism. Selection depends on differential pressure and process conditions.

Piston Type Control Valve

A piston type control valve is associated with flow or pressure regulation duties. Its operating characteristics differ from those of a piston isolation valve.

Stainless Steel Piston Check Valve

A stainless steel piston check valve may be selected where compatible stainless construction is required. It is not included in the supplied product specifications.

Piston Steam Valve Applications

Piston valves are sometimes considered for steam isolation duties where the complete valve design is suitable for the operating conditions.

Buyers searching for a piston steam valve or piston valve steam applications should check the pressure-temperature rating, body material, sealing arrangement and relevant testing requirements.

The supplied specifications list graphite sealing and a temperature of 400°C. These details should be reviewed alongside the applicable pressure class and approved technical datasheet.

The highest listed temperature should not be treated as confirmation that every valve configuration is suitable at that temperature.

Frequently Asked Questions

FAQs About Piston Valves

Answers to common questions about piston valve types, working principles, materials and applications.

What is a piston valve?

A piston valve uses a piston-like closing element and sealing arrangement to provide suitable flow isolation.

What is the working principle of a piston valve?

The piston moves through the sealing arrangement as the valve opens or closes. Its position determines whether flow is permitted or isolated.

What is the difference between a flanged and screwed piston valve?

A flanged piston valve connects through bolted flanges, while a screwed piston valve uses threaded connections. The supplied flanged classes are 150 and 300; the screwed class is 800.

What size range is listed?

Both supplied configurations list sizes from ½ inch to 6 inches. Confirm individual size availability before ordering.

Are piston valves suitable for steam?

Some piston valve designs are used for suitable steam isolation duties. Pressure-temperature suitability and the complete valve construction must be verified.

What is a spring loaded piston check valve?

It is a non-return valve design that uses a piston and spring mechanism to help prevent reverse flow. It differs from a piston shut-off valve.

What body materials are listed?

The supplied specifications list ASTM A216 WCB and forged construction for the body and bonnet.

What sealing material is specified?

Graphite is listed as the sealing material for both flanged and screwed piston valves.

Is a piston valve the same as a piston check valve?

No. A piston shut-off valve is intended for isolation duties. A piston check valve is intended to restrict reverse flow.

Can I request a piston valve quotation for Mumbai or another city in India?

Yes. Ultra Valves Automation Pvt. Ltd. welcomes industrial piston valve enquiries from Mumbai and across India. Share your specifications and quantity to request a quotation.
