Overview
The BWZRHP electric insulation regulating valve is suitable for occasions that require insulation. When the crystallization temperature of the process medium is lower than the ambient temperature or the fluid temperature decreases, causing an increase in viscosity or solidification of the fluid, a steam insulation jacket device is added at the valve body and upper valve cover to meet the process control requirements of the process medium.
Product Details
Electric insulation control valveThe valve core adopts an upward guiding structure, with a compact valve structure and S-shaped channels, which reduces pressure drop loss, increases flow rate, has a wide adjustable range, and high accuracy of flow characteristics, in compliance with the IEC534-2-1976 standard.Electric insulation control valveEquipped with a 3810 series (PSL series) electronic electric actuator and a low flow resistance regulating valve body, the electric actuator is an integrated structure with a servo amplifier inside. By inputting control signals (4-20mADC or 1-5VDC) and power supply, the valve opening can be controlled to adjust working parameters such as pressure, flow rate, liquid level, and temperature.Electric insulation control valveThe leakage rate meets the ANSIB16.104 standard.
