Pneumatic diaphragm jacketed control valve
Engineered valve solutions, ball and butterfly valves, actuators, high pressure chokes, valve positioners, sensors, regulators, free control valve sizing.
IQ(D)10J Series of Intelligent Jacketed Insulation Control Valve mainly applied to the occasions of thermal insulation, full the heat medium into the gap between valve body and metal jacket to keep thermal insulation and prevent fluid crystallization occurs, as well as the increase of viscosity, which due to the temperature reduction.
ZM10 series muti-springs pneumatic reinforce actuator, makes the valve realize the conversion of normal close and normal open on site easily, the spring can be effectively protected from the corrosion to prolong the service life of actuator and convenient for customers operation. The actuator and the intelligent valve positioner are connected pipeless to strengthen the antisemitic performance, stability and precision adjustment, to meet to exactly control of the working conditions.
Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions. The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals. These control signals, traditionally based on 3-15psi (0.2-1.0bar), more common now are 4-20mA signals for industry, 0-10V for HVAC systems, and the introduction of "Smart" systems, HART, Fieldbus Foundation, and Profibus being the more common protocols.
A control valve consists of three main parts in which each part exist in several types and designs:? Valve's actuator? Valve's positioner? Valve's body
