Here we'll look at the design and ideal uses of Swagelok's Thermal Service Ball Valve (T60M Series). With its innovative metal seat, this special purpose valve is designed to maintain a seal with a minimum seat load against the ball.
The Swagelok T60M Series thermal service ball valve features a spring-like metal seat designed for maintaining a seal with minimum seat load against the ball. It is available in 316 stainless steel or carbon steel, with Grafoil packing and alloy X-750 seats.
This valve is specifically intended to resist contamination in thermal liquid applications and is suitable for use with high-viscosity thermal fluids. (Note: we advise against using the valve with hot gases or low-viscosity fluids, as these may remove the factory-applied lubricant, leading to premature seat wear.)
The Swagelok T60M Series thermal service ball valve exceeds performance criteria set by the Fire Test Standard API 607, 6th edition. This certification underscores the valve's capability to maintain its integrity and functionality in extreme conditions, confirming its suitability for applications where safety in the face of fire hazards is top priority.
Design features
The valve's smooth, quarter-turn rotary operation resists outside contaminants and reliably contains thermal liquids, preventing leaks and ensuring safe transport of high-viscosity fluids. Its spring-loaded metal seats provide leak-tight sealing up to 850°F (454°C) and down to -65°F (-53°C), and work effectively in both low- and high-pressure systems up to 1000psi (68.9 bar), enhancing reliability in high-temperature applications.
Featuring encased 8-bolt construction, the valve counters differential thermal expansion during rapid temperature cycling, maintaining structural integrity and reducing the risk of leaks or damage from varying expansion rates.
All Swagelok's thermal service ball valves undergo testing with pure nitrogen at 50 psig (3.4 bar) to ensure leak-tight integrity of the ball seats, as per FCI 70-2 Class VI specifications. Stem packing and body seals are checked for no visible leakage using a liquid leak detector.
Seal kits
Seal kits for T60M valves include an array of components: the ball, seats, packing, flange seals, stem bearings, back seats, packing supports, stem springs, lubricant, sealant, and instructions for use.
