Product Detail

1. Product Overview

Electric insulation jacket control valve manufactured by Shanghai Chuanhu Valve Co., Ltd. adopts top-guided plug structure with compact overall layout and S-shaped streamlined flow channel. It features low pressure drop loss, large flow capacity, wide adjustable range and high-precision flow characteristics, complying with IEC534-2-1976 standard.

This valve is assembled with 3810 series (PSL series) integrated electronic electric actuator and low flow resistance valve body. The electric actuator is an all-in-one unit built with servo amplifier. It can adjust valve opening by receiving control signal (4-20mADC or 1-5VDC) and power supply, realizing precise regulation of pressure, flow, liquid level, temperature and other process parameters.

Product Features

Compact volume, light weight, simple wiring, large flow rate and high regulation accuracy.
Leakage performance meets ANSI B16.104 standard.

Application Scope

Model ZD(R)SBW-P(M) is designed for working conditions requiring medium heat preservation. If the crystallization temperature of process medium is lower than ambient temperature, or the medium viscosity rises/solidifies with temperature drop, a steam insulation jacket is installed on valve body and upper bonnet to maintain medium fluidity and satisfy process control requirements.
