The HTS single-seat control valve is a pneumatic control valve with a single-seat, single-valve core structure, equipped with a pneumatic diaphragm or piston actuator. It is used for continuous and precise control of the flow rate, pressure, temperature, and liquid level of the medium in pipelines.
Our control valves are engineered with optimized flow paths and control trims to deliver accurate, repeatable control across a wide operating range.
Specialized designs are available for high pressure, high temperature, corrosive, abrasive, and high differential pressure applications.
We offer a wide selection of valve body and trim materials, carefully selected to match process media and service conditions.operation.
The HTS single-seat control valve is a pneumatic control valve with a single-seat, single-spool structure, equipped with a pneumatic diaphragm or piston actuator. It is used for continuous and precise control of flow rate, pressure, temperature, and liquid level of the medium in pipelines.
This series of valves features a compact structure, low leakage, and high control accuracy, making it suitable for industrial automation systems requiring high sealing performance and control stability.
Structural Features
1. Single-seat structure design
Adopts a single valve seat and single valve spool, effectively reducing internal leakage and meeting high sealing requirements.
2. Balanced or unbalanced valve spool
Can be selected according to working conditions, balancing control performance and actuation force requirements.
3. Pneumatic actuator
Optional pneumatic diaphragm or piston type, with stable operation and fast response.
4. Modular accessory configuration
Can be configured with valve positioner, filter regulator, limit switch, solenoid valve, etc.
Core Advantages
1. Low leakage
Single-seat structure, superior sealing performance compared to double-seat valves.
