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.
