Swagelok SS-83TS8 3-Piece High Pressure Ball Valve with PTFE Seat

Swagelok SS-83TS8 is a genuine OEM 3-piece trunnion-style high pressure ball valve, part of the renowned 83 Series from Swagelok, a global leader in fluid system components. This valve is engineered for durable, leak-tight service in both high- and low-pressure applications, providing reliable shutoff in a compact, maximum-flow design.

Designed specifically for use with 1/2 inch outer diameter tubing, this valve features integral Swagelok® tube fitting ends on both ports, eliminating the need for additional adapters and ensuring a reliable, leak-proof connection upon proper installation.

Key Features & Benefits

Trunnion-Style Design: The trunnion ball design minimizes operating torque and reduces seat wear, ensuring a long cycle life and consistent performance even under high differential pressure.

High Pressure Capability: Rated for working pressures up to 1500 PSIG (103 bar) at 100°F (37°C) , making it suitable for demanding industrial applications.

PTFE Seat Material: Standard PTFE seats provide excellent chemical resistance and reliable sealing performance across a wide temperature range.

316 Stainless Steel Construction: The valve body is constructed from corrosion-resistant 316 stainless steel, ensuring durability and longevity in harsh environments.

Compact, Maximum-Flow Design: The valve's orifice size of 0.187 inches (4.7 mm) and flow coefficient (Cv) of 1.0 allow for efficient system flow while maintaining a compact footprint.

Low Emissions Certified: Certified to meet low emission standards, supporting environmental and safety requirements.

Phenolic Handle: Features a durable, easy-to-grip black phenolic handle for reliable manual operation.

Standard Cleaning and Packaging (SC-10): Cleaned and packaged according to Swagelok's standard practices, suitable for a wide range of industrial and general service applications.

Applications

The Swagelok SS-83TS8 is ideal for a wide variety of industrial applications requiring reliable shutoff in a compact, high-pressure package:

Oil and Gas: Sample systems, hydraulic control panels, and high-pressure lines .

Petrochemical and Chemical Processing: Isolation of instruments and control of process fluids.

Power Generation: Fuel systems and high-pressure instrumentation.

General Industrial: Hydraulic systems, test benches, and high-pressure water or gas services.

Why Choose the 83 Series?

Swagelok's 83 Series trunnion ball valves are known for their robust construction and consistent performance. The trunnion design supports the ball, reducing operating torque and wear on the seats. This makes the valve suitable for applications with high differential pressure or where frequent operation is required. The series is available with a variety of end connections, including Swagelok tube fittings and NPT, and in both 2-way and 3-way switching configurations .

Important Consideration: The SS-83TS8 is a manual valve designed for full open or full closed positions to ensure optimal performance and longevity. Valves that have not been operated for an extended period may exhibit a higher initial breakaway torque.
