Control valves are valves accustomed to control conditions for example flow, pressure, temperature, and liquid level by fully or partly opening or closing as a result of signals caused by controllers that compare a "setpoint" to a "process variable" whose value is supplied by sensors that monitor alterations in such conditions.
Control valves are valves accustomed to control conditions for example flow, pressure, temperature, and liquid level by fully or partly opening or closing as a result of signals caused by controllers that compare a "setpoint" to a "process variable" whose value is supplied by sensors that monitor alterations in such conditions.The outlet or closing of control valves is generally done instantly by electrical, hydraulic or pneumatic actuators. Positioners are utilized to control the outlet or closing from the actuator according to electric, or pneumatic signals. These control signals, typically according to 3-15psi (.2-1.0bar), more prevalent now are 4-20mA signals for industry, -10V for Heating and cooling systems, and the development of "Smart" systems, HART, Fieldbus Foundation, and Profibus to be the more prevalent protocols.
A control valve includes three primary parts by which each part appear in several types and fashions : Valve's actuator, Valve's positioner, Valve's body.
Nowadays with the introduction of the modernized industrial automatic controlling system progressing, the necessity to control valve elevated. Shinjo because of so many years development and research, developed ZH series direct travel control valve and ZR series position travel control valve. Compact structure, advanced operation actuator system. Relevant medium are Liquid, Gas and Steam. Shinjo control valve rich in durability and stability, simple for type selecting. Structure simplified, reduced the spares in great quantity, more convenien for valve maintenance and reduced the constant maintenance cost.
