Product Description
Pneumatic Single-Seat Globe Control Valve (GAZJHP)
This product is composed of pneumatic multi-springs, pneumatic actuator, and a low flow resistance sleeve. The valve utilizes a balanced valve core, ensuring small unbalanced forces, high permissible pressure differentials, and steady operation. Compared with ordinary single and double seat-regulating valves, it features low noise, a simple structure, and convenient assembly and dismantling.
The valve shape is compact, the body is lightweight, and it offers high performance and capacity. It is a new type of general regulating valve suitable for common fluid mediums and industrial control system conditions.
Temperature Specifications: Working temperature for standard structures can reach up to 250 Deg C. For temperatures exceeding 250 Deg C, a Heat Radiator is required, and the trim must undergo heat treatment.
