Bray Commercial ST2-05-2-02 Ball Valve
The Bray Commercial ST2-05-2-02 Ball Valve is a high-precision 1/2" 2-way characterized control valve engineered specifically for technical HVACR water and low-pressure steam applications. Built with a forged brass body and featuring a stainless steel ball and stem, this SoftTouch 2 (ST2) series valve ensures long-term reliability in demanding building automation environments. With a flow coefficient (Cv) of 1.9, it delivers an equal percentage flow characteristic, providing the linear heat output necessary for stable terminal unit control in fan coils, VAV reheat coils, and chilled beams.
This model utilizes a high-temperature 200 PSI close-off rating and is designed for seamless field integration with direct mount actuators. The blowout-proof stem and self-centering stem bushing design minimize torque requirements, extending the service life of both the valve and the linked 24VAC/DC or 120VAC electric actuators. Whether managing chilled water, hot water, or up to 50% glycol solutions, the ST2-05-2-02 provides the mechanical durability and ANSI Class IV leakage protection required by modern mechanical contractors.
Key Benefits- Optimized Control Resolution: The characterized insert provides equal percentage flow, eliminating the erratic temperature swings common with standard ball valves.
- Rugged Construction: Stainless steel trim and a forged brass 2-piece body withstand temperatures up to 284°F and 15 PSI saturated steam.
- Actuator Longevity: Low operating torque allows for the use of smaller, cost-effective actuators while reducing mechanical wear.
- Zero Leakage Performance: Dual EPDM O-rings and PTFE seats ensure a tight seal and prevent bypass in the closed position.
- Universal Compatibility: Standard NPT threaded connections allow for fast retrofitting of existing globe or ball valve assemblies.
What is the maximum differential pressure for this valve?
The Bray ST2-05-2-02 is rated for a close-off pressure of 200 PSI, making it suitable for high-rise hydronic systems where differential pressure across the seat is a concern.
Can I use this valve for steam applications?
Yes, the ST2 series with stainless steel trim is rated for saturated steam up to 15 PSI, making it a versatile choice for both hydronic and low-pressure steam loops.
Does this valve require special tools for actuator mounting?
No, it features a direct-mount flange and a self-centering stem bushing, which allows for quick, tool-free alignment of Bray VA and VAM series actuators.
