The versatile High Pressure Control Valve can be used as a Dump Valve or Pressure Regulator with the addition of a pressure pilot. Operated by control of a pneumatic input signal to open or close the valve depending on its configuration. Optional
The valves you have are 572 2 and 573 2 zone valves. There should be 3 terminals marked #1 #2 and #3. #1 and #2 should have 24 volts going to them when the thermostat is calling for heat. If you have 24 volts the valve should open after 1½ minutes.
The Characterized Control Valve combines the high close off capabilities of a ball valve with a characterized disc that ensures a true equal percentage flow characteristic to achieve superior light load flow control.
Jun 15 2020 The valve actuator is one of the important control valve parts used to fully open or fully close the valve. Actuators receive a positioning signal for controlling or regulating valves. They have different types such as gear actuators electric motor actuators pneumatic actuators solenoid actuators and hydraulic actuators.

Dec 08 2020 Standard control valves can handle a wide range of control applications. The range of standard applications can be defined as being encompassed by atmospheric pressure and 6000 psig 414 bar 150F 65C and 450F 232C flow coefficient Cv values of 1.0 and 25000 and the limits imposed by common industrial standards. Certainly corrosiveness and
May 02 2018 The two types of control valves are linear motion and rotary motion. Linear Motion Linear motion valves have a closure member that moves with a linear motion to modify the rate of flow through the valve. Linear motion valves are generally named

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. They create two actions and have two exhaust ports which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Also known as 4 way and 5/3 closed center valves.
Directional Control Proportional Valves #GP02531V. Parker’s family of 3 position 4 way proportional directional control valves come standard with closed or float center spools and are capable of flows up to 32 lpm 8.5 gpm and pressures as high
Oct 29 2019 A If wanting to minimize pumping energy the optimum valve would be one with minimum pressure loss a large Cv. But this would mean that the flow rate response to valve position controller output would be nonlinear. Even with the linearizing effect of an equal percentage valve characteristic a valve with minimal pressure losses would have a nonlinear
Feb 08 2022 Diaphragm valves are characterized by a flexible disc that contacts a seat at the top of the valve body and forms a seal. The diaphragm is flexible and pressure responsive it transmits force to open close or control a valve. While
Other control valves have linear flowing characteristics. A butterfly valve’s design does not allow it to have linear flow characteristics due to the shape of the disc and its relationship to the pipe thus making it more difficult to control. Consider adding instrumentation and a positioner to the valve to help gain more precise control of
