Swagelok SS-63TS8-33C Stainless Steel 3-Piece 60 Series Ball Valve with Pneumatic Actuator

Swagelok SS-63TS8-33C is a high-performance, pneumatically actuated ball valve from the renowned 60 Series of general purpose and special application ball valves. This engineered fluid system component features a 316 stainless steel 3-piece body construction with 1/2 in. Swagelok tube fitting end connections, making it ideal for reliable flow control in industrial instrumentation, process analyzers, and fluid handling systems.

This complete assembly integrates a 133 Series pneumatic actuator configured for normally closed (NC) spring-return operation, providing automatic, remote flow control capabilities. The valve is engineered for low-maintenance service with reinforced PTFE seats and a pressure rating of 2200 PSIG at 100°F (151 BAR at 37°C).

Key Features & Benefits

Superior Materials: Constructed from 316 stainless steel for exceptional corrosion resistance and durability in demanding environments.

Precision 3-Piece Design: The 3-piece swing-out design enables easy in-line maintenance without removing the valve from the system, reducing downtime.

Reinforced PTFE Seats: Features reinforced PTFE seat material with a unique conical disc spring design that compensates for wear and pressure changes, ensuring consistent, leak-tight sealing.

Reliable Sealing System: Incorporates live-loaded, two-piece V-ring stem packing that automatically adjusts for pressure and temperature fluctuations, extending seal life .

Integrated Pneumatic Actuation: Factory-assembled with a 133 Series pneumatic actuator in normally closed configuration for reliable automated operation.

Standard Cleaning: Supplied with standard cleaning and packaging specification (SC-10), suitable for general service applications.

Engineering Design Features

The 60 Series ball valve incorporates several advanced engineering features that distinguish it from conventional ball valves:

Live-Loaded Packing: The two-piece V-ring stem packing is constantly energized by springs, maintaining a consistent seal despite temperature cycling or normal wear.

Compensating Seat Design: Reinforced PTFE seats are supported by conical disc springs that maintain sealing contact with the ball across varying pressure and temperature conditions.

Blowout-Proof Stem: The stem is internally inserted and retained, preventing accidental ejection even if the packing nut is removed under pressure.

Swing-Out Accessibility: The center section of the 3-piece body can be swung out without disturbing the end connections, providing complete access for maintenance.

Applications

The SS-63TS8-33C is engineered for reliable performance in a wide range of industrial applications requiring automated flow control:
