What is the difference between 2-piece and 3-piece ball valve configurations?

A 2-piece ball valve has a body joined at one end, while a 3-piece design allows the centre body section to be removed for in-line maintenance without disturbing the end connections. Choose 3-piece valves where regular inspection or seat replacement is anticipated.

Can I automate this ball valve with a pneumatic actuator?

Yes. The valve includes an ISO 5211 mounting pad, enabling direct installation of Revo double-acting or single-acting pneumatic actuators. Actuator sizing charts are available for Class 150 and Class 600 valves across various air supply pressures.

What seat material is used, and what is the temperature limit?

Standard seat material is PTFE, suitable for temperatures from approximately –30°C to +200°C depending on pressure and media. For higher temperatures or specific chemical compatibility, contact our engineers for alternative seat options.

Is this valve suitable for steam service?

Soft seated PTFE ball valves are generally recommended for saturated steam at lower pressures and temperatures within PTFE limits. For high-pressure or superheated steam, metal-seated ball valves or globe valves may be more appropriate.

What testing standards do these valves meet?

Crane soft seated ball valves are tested per API 598, which covers shell, back seat, and closure tests. Certificates can be provided on request.

Overview

The Crane Soft Seated Ball Valve is a robust quarter-turn isolation valve designed for reliable shut-off in industrial piping systems. Available in 2-piece and 3-piece configurations, these valves feature a solid ball design that delivers true full-port flow characteristics, minimizing pressure drop and enabling efficient pigging operations.

Constructed to meet BS EN ISO 17292 and API 598 standards, these ball valves are suitable for a wide range of process fluids. The anti-blow out stem design provides an additional layer of safety by preventing stem ejection under pressure build-up. An ISO 5211 actuator mounting pad is integrated into the body, allowing direct installation of pneumatic or electric actuators for automated control.

Standard body materials include WCB (carbon steel) and CF8M (316 stainless steel), making these valves suitable for both general service and corrosive media applications. PTFE seats and seals ensure tight shut-off and chemical compatibility across a broad temperature range.
