P-series Pneumatic Single Seat Regulating Valve
The company’s P series pneumatic single-seat regulating valve is designed with a modular concept, allowing for arbitrary combination and interchangeability of its main components. It features a compact structure, small size, light weight, and sensitive action. The flow channel boasts S streamline advantages, minimal pressure drop loss, high flow capacity, precise flow characteristics, and easy maintenance. This makes it especially suitable for applications requiring minimal leakage tolerance, low pressure differentials across the valve, and clean fluid operation. Widely utilized in the petroleum, chemical, electric power, textile, paper industries.

【Product Characteristics】
1. The company’s regulating valves feature an S-shaped valve body, offering excellent pressure resistance and reliable structural strength to prevent common defects such as deformation and increased internal leakage during installation. The inner flow channel of the valve ensures low flow resistance, while the S-shaped flow channel minimizes overall flow resistance, providing a wide adjustable range and high flow characteristic accuracy.
2. Depending on different working conditions, various structures can be selected with completely interchangeable throttling components, also known as valve internals. Flow characteristics include equal percentage, straight line, fast opening, and other optional options.
3. The P series pneumatic single-seat valve internals consist of a seat, spool, and stem with an upper guide structure. This design offers advantages such as compact structure, light weight, high adjustment accuracy, minimal pressure drop loss, accurate flow characteristics,
large guiding area, and anti-vibration properties. It is particularly suitable for environments where minimal leakage and small pressure differences between the front and back of the valve are required.
