Pneumatic angle seat valve
With the smart positioner of the control valve, the valve position sensor, electric control system and a microprocessor to do continuous position control, can also be through the internal function of the realization of continuous process control ( PID function).
U-ideal instrument pneumatic angle seat valve with 316stainless steel as the main manufacturing material, widely used in beer, textile printing and dyeing and bleaching, pharmaceutical and medical equipment, food processing machinery, rubber, organic and inorganic chemicals, disinfection sterilization, water treatment and other industries, is suitable for the medium is water, liquid, gas, steam, minor corrosive gas and liquid, and the electromagnetic valve and other valves compared with investment, economic, safe use, maintenance-free, long life characteristics.
Compared with traditional angle seat valve, it has the following characteristics:
1, visual position indicator: Which can be connected with the limit switch or emergency manual device.
2, easy to install: Pneumatic head can rotate360 o. Can be easily installed a two limit switch.
3, advanced pneumatic controller: Thickening of engineering plastics shell, safe and reliable. Low wear of the piston structure, large capacity and low air consumption. Internal components of self lubrication, maintenance free
4, with a variety of control mode: Normally open, normally closed, double action.
5, requires a smaller pneumatic actuators: Fluid from the stem above the inflow, the optional smaller control head.
6, easy to connect: MAMUR standard connector, embedded metal connector.
7, long-life Guide: Lease stem-shaped Teflon ( PTEE ) sealed, avoid the import of stolen goods. Self lubrication, maintenance free. Stem through the special treatment to ensure the best fixed, and can
Automatic position correction.
8, no water hammer effect, fluid flows from the stem below, water hammer ( the impact force of water is absorbed ).
9, advanced valve mechanism: Flow than ordinary angle seat30%, smaller volume, fluid flow and. Stainless steel valve body 316, teflon seal, high temperature resistance, corrosion resistance.
IQ(D)60 Series of Intelligent Angle Control Valve uses modular design and impact structure. The varieties combination of the trim components make it applicable for high pressure head, high viscosity paste or containing granular fluid conditions, as well as sites like serious being flashed, cavitated and pipe direction change needed.
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
