ZJHP气动调节阀Product Overview

ZJHP Pneumatic Control Valve is an automated control device powered by compressed air, mainly used for precise regulation of pressure, flow, temperature,  liquid level of media such as gas, liquid,  steam. It consists of a multi-spring pneumatic diaphragm actuator  a low-flow-resistance single-seat valve body, featuring compact structure, light weight, sensitive operation, S-shaped fluid channel, low pressure drop, high valve capacity, accurate flow characteristics,  convenient installation  disassembly. This valve is widely applied in industrial automatic control systems in petrochemical, power, pharmaceutical,  other industries, especially suitable for applications requiring small leakage   the pressure difference before  after the valve is  large. The product is available in standard, regulating shut-off, bellows sealed,  jacketed types, with nominal pressure ratings of PN16, 40, 64, nominal diameter range DN20～300,  applicable fluid temperature range  -200℃ to +560℃.5
