TE-6311V-2 Johnson Controls Probe

Overview

The Johnson Controls VG7241PT+3008E is a pneumatic control valve assembly designed for precise modulating control of water or steam in commercial HVAC systems. This 1-1/4 inch two-way valve features a cast bronze body and is configured as normally open, meaning it defaults to the open position upon loss of pneumatic pressure. Equipped with a robust pneumatic actuator featuring a 9 to 13 psi spring range, this assembly ensures reliable, rapid response times and consistent cycling to maintain stable environmental control.

Features

• Two-Way Normally Open Configuration: The valve remains open via spring return during power or pressure loss, providing a reliable fail-safe operation.
• Premium Material Construction: Built with a rugged cast bronze body, a stainless steel stem, and durable brass trim to resist corrosion and ensure long-term durability.
• Equal Percentage Flow Characteristic: Delivers superior control loop stability and precise regulation across varying flow demands.
• Proven Cycle Life: Engineered and rigorously tested to withstand over one million cycles for maximum operational longevity.
• In-Place Serviceability: Designed to allow convenient valve repacking while still installed in the piping system, reducing maintenance downtime.
