Pneumatic single seat control valve
Engineered valve solutions, ball and butterfly valves, actuators, high pressure chokes, valve positioners, sensors, regulators, free control valve sizing.
ZJHP-1 Series of Intelligent single-seat control valve lined F, its inner cavity of the valve body, plug, stem are lined with 3mm thickness fluorinated ethylene propylene (FEP), which resistant to all chemical fluid corrosion(including concentrated sulfuric acid, alkali and aqua regia). Using the double sealing which are the PTFE bellows and packing, in case the damage of the bellows happened, control valve packing can rise to be the second protective sealing. It also has characteristics of impact structure, small volume, light weight, good corrosion resistance performance etc.
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
