The small caliber single seat regulating valve mainly consists of three parts: pneumatic actuator, valve body, and accessories. It is a high-performance regulating valve. The actuator is powered by clean compressed air, accurately positioned with the valve positioner, receives 4-20mA electrical signals or 20-100KPa gas signals, drives the valve body to move, changes the flow area between the valve core and the valve seat, and thus achieves the function of regulating the flow rate.
Small caliber single seat regulating valves are designed for heavy load conditions. The valve body structure is compact, the fluid channel is S-shaped, the pressure drop loss is small, the flow rate is large, the adjustable range is wide, and the flow characteristic accuracy is high. The valve core can select a wide range of CV values. The valve seat closing performance complies with IEC and JIS standards. The regulating valve is equipped with a multi spring thin film actuator, which has a small structure and high output force.
Small caliber single seat regulating valve internal components:
1). Valve core form: single seat plunger type valve core
2). Traffic characteristics: equal to hundred, linear
3). Materials: stainless steel, stainless steel overlay with Stellite alloy, titanium, and corrosion-resistant alloys, etc
Characteristics of small caliber single seat regulating valve:
1. Fine decoration, good control, good sealing, excellent design, and quality
2. Technology, structure, smooth flow, rapid response, alternative to imports
3. Low pressure drop loss, stable output force, high flow coefficient, and equal smooth cross-section of the channel.
4. Wide adjustment range, high precision of flow characteristics, top guide structure, and easy operation of the handwheel.
5. Good sealing performance: The corrugated tube and packing made of polytetrafluoroethylene material are double sealed to ensure no leakage.
6. The valve body is designed according to the principles of fluid mechanics, with a low flow resistance flow channel of equal cross-section, and the rated flow coefficient is increased by 30%.
