Socket Weld Forged Steel Ball Valve
Socket Weld Forged Steel Ball Valve
Socket weld forged steel ball valves provide quarter-turn on/off isolation for small-bore industrial piping systems. Material selection, pressure rating, seat design and operating temperature should be matched to the process medium and service conditions.
Key Features
Forged Steel Body: Available in carbon steel and stainless steel grades, subject to the specified valve configuration.
Socket Weld Ends: Provide permanent welded connections for compatible piping systems.
Quarter-Turn Operation: Enables quick manual shut-off with a 90-degree handle movement.
Optional Actuation: Pneumatic or electric actuation may be available, subject to mounting compatibility and operating torque.

Frequently Asked Questions
Q: What is the advantage of a socket weld ball valve?
A: It provides a permanent welded connection for compatible small-bore piping and eliminates the threaded joint as a potential leakage path.
Q: How do I select the correct pressure class?
A: Confirm the required pressure rating, operating temperature, process medium and applicable piping requirements. Verify the valve's pressure–temperature limits before selection.
Q: How should I choose between RPTFE and PEEK seats?
A: Compare the medium, operating temperature, pressure and required mechanical properties against the verified limits of the complete valve assembly.
Q: Can the valve be supplied with an actuator?
A: Pneumatic or electric actuation may be available, depending on the valve design, mounting arrangement, operating torque and control requirements.
Q: What inspection documents are available?
A: Material test reports, pressure-test records and additional inspection documents can be agreed upon at the quotation stage.
