Pneumatic Globe Sleeve Control Valve

Parameters of Pneumatic Globe Sleeve Control Valve
  1. The use of a balanced spool structure, axial imbalance force is small, allowing large pressure, good stability. Sleeve interchangeability is good, easy disassembly, easy maintenance.
  2. All-metal spool structure for a variety of work occasions, to Class IV leaking standards, soft seal structure spool to VIgrade leakage standards.
  3. The valve body is designed according to the principle of fluid mechanics, such as low flow resistance flow path, adjustable range, the inherent adjustable ratio of 50: 1, rated flow coefficient increased by 30%.
  4. The actuator adopts a multi-spring structure, a height reduction of 307%. Weight reduction by 30%.

5. Bellows sealing control valve, the movement of the stem to form a complete seal, blocking fluid leakage.

Pneumatic Globe Sleeve Control Valve

Description

Pneumatic Globe Sleeve Control Valve

Introduction

The pneumatic diaphragm sleeve control valve is a pressure balance type regulating valve. Equipped with a multi-spring actuator, the overall structure of compact, heavy light, good stability. The fluid channel was 3 streamlined, the pressure drop loss is small, allowing large pressure, noise, circulation capacity. Widely used in precise control of gas, liquid, and other media process parameters such as pressure, flow, temperature, a liquid level maintained at a given value. Particularly suitable for large flow, large pressure, leakage requirements are not high occasions.

This series of products are standard and adjustable cutting type, bellows sealing type, jacket insulation, and other varieties. Products nominal pressure level households ~ 10, 16, 40, 64, body diameter range from DN20 ~ 500, the application of fluid temperature from -196 ℃ ~ + 560 ℃, within the scope of a variety of grades. Leakage standards are ClassIV, Class V, and Class VI. Flow characteristics are linear or equal percentages. Variety of varieties, specifications to choose from.
