Johnson Controls VG7241CT Valve

The Johnson Controls VG7241CT is a high-performance 1/2 inch NPT globe valve engineered specifically for precise control of hot water, chilled water, and saturated steam in commercial HVAC systems. This 2-way normally open valve features a 0.73 Cv rating with an equal percentage flow characteristic, ensuring stable modulating control even at low flow rates. Built to ASME B16.15 Class 250 standards, the cast bronze body and brass trim provide a rugged solution for high-static pressure applications, capable of handling fluid temperatures from 35?F to 284?F and saturated steam up to 38 psig. The standard threaded stem and push-down-to-close action allow for seamless integration with a wide variety of VG7000 series pneumatic and electric actuators, such as the VA-7150 or V-3000 series. Designed for long-term field service, this valve utilizes a replaceable ring packing to maintain a tight seal, reducing maintenance downtime and preventing seat leakage in demanding hydronic loops.

• Precise Flow Modulation: The equal percentage characteristics provide superior control in the first half of the stroke, ideal for terminal unit applications.
• Industrial-Grade Durability: The cast bronze body and brass trim resist corrosion and are rated for ANSI Class 250 static pressure.
• Versatile Media Compatibility: Rated for water, glycol solutions up to 50%, and low-pressure steam, making it a versatile pick for mechanical rooms.
• Field Serviceability: Includes replaceable ring packing, allowing technicians to service the valve in-line without full system drainage.
• Reliable Shut-off: Tested to ANSI Class IV leakage standards, ensuring minimal energy loss when the system is not in demand.

What actuators are compatible with the VG7241CT?
This valve is designed for use with Johnson Controls VG7000 Series actuators. It features a standard threaded bonnet that fits various electric (VA-7000, VA-4233, VA-715x) and pneumatic (V-3000, MP800) series depending on your control signal and force requirements.

Can this valve be used for steam applications?
Yes, the VG7241CT is rated for saturated steam up to 38 psig. For steam service, it is recommended to install the valve with the stem in a horizontal position to protect the actuator from heat and to ensure longevity of the brass seat.

What is the fail-safe position of this model?
As a normally open valve with push-down-to-close (PDTC) action, the valve remains in the open position when no force is applied to the stem. The final fail-safe position is determined by the specific spring-return actuator paired with the valve body.
