Product Description

The Honeywell MP953C 1026 2 is a pneumatic valve actuator designed for precise control in HVAC systems. It features a 5-inch diameter and utilizes a rolling diaphragm mechanism, ensuring long life and low hysteresis. This actuator is engineered for direct-acting applications, with a spring range of 4 to 11 psi, making it suitable for proportional control of steam or hot and cold liquids. Its robust construction allows for easy attachment to valve assemblies such as the V5011, V5013, and VGF series, and it can be installed after the valve piping.
