ZZYM ZZYM-16 ZZYM-40 Self-actuated control valve

Overview

ZZYM ZZYM-16 ZZYM-40 Self-actuated control valve is an energy-saving control device that does not need external driving energy, relies on the pressure of the regulated medium itself as power and its pressure change, and automatically adjusts according to the preset setting value. It integrates many functions of detection, control and execution into one valve, forming an independent instrument control system. The product is composed of balanced sleeve valve body, bellows (sleeve) balancer and actuator. It is a new generation of valve products in line with national standards.

Features of ZZYM ZZYM-16 ZZYM-40 Self-actuated control valve

1. Energy saving automatic control system without additional driving energy, low equipment cost, and suitable for various working conditions;

2. Simple structure and small maintenance workload;

3. The set point is adjustable and the range is wide, which is convenient for users to continuously adjust within the set range;

4. The cylinder type mechanism has a wide range of testing pressure resistance, and its action is sensitive and reliable;

5. The pressure balance mechanism is adopted in the valve to make the regulating valve responsive, accurate in control and large in allowable differential pressure;
