How much does PARKER solenoid valve cost

Working principle of PARKER solenoid valve

The PARKER solenoid valve has a sealed chamber with through holes at different positions, each connected to a different oil pipe. The middle of the chamber is a piston, and there are two electromagnets on both sides. The valve body will be attracted to which side when the magnetic coil on the other side is energized. By controlling the movement of the valve body, different oil discharge holes can be opened or closed, while the oil inlet hole is normally open. Hydraulic oil will enter different oil discharge pipes, and then push the piston of the oil cylinder through the pressure of the oil. The piston drives the piston rod, which in turn drives the mechanical device. In this way, the mechanical motion is controlled by controlling the current on and off of the electromagnet.

PARKER solenoid valve is an industrial equipment controlled by electromagnetic force, which is an automation basic component used to control fluids. It belongs to actuators and is not limited to hydraulic and pneumatic systems. It is used in industrial control system to adjust the direction, flow, speed and other parameters of medium. Electromagnetic valves can be used in conjunction with different circuits to achieve the desired control, while ensuring the accuracy and flexibility of the control. There are many types of solenoid valves, and different solenoid valves play a role in different positions of the control system. Commonly used ones are one-way valves, safety valves, directional control valves, speed regulating valves, etc.

Selection criteria for PARKER solenoid valve

The selection of PARKER solenoid valves should first follow the four principles of safety, reliability, applicability, and economy. Secondly, the selection should be based on six aspects of on-site conditions (i.e. pipeline parameters, fluid parameters, pressure parameters, electrical parameters, action mode, and special requirements).

Selection criteria for PARKER solenoid valve:

1. Select the solenoid valve based on pipeline parameters: diameter specification (i.e. DN), interface method

1) Determine the diameter (DN) size according to the on-site pipeline inner diameter size or flow requirements;

2) Interface method, generally>DN50 requires flange interface, ≤ DN50 can be freely selected according to user needs.

2. Select the material and temperature group of the solenoid valve based on fluid parameters

1) Corrosive fluids: corrosion-resistant solenoid valves and all stainless steel should be selected; Edible ultra clean fluid: It is recommended to use food grade stainless steel solenoid valves;

2) High temperature fluid: It is necessary to choose electromagnetic valves made of high-temperature resistant electrical materials and sealing materials, and to choose piston type structures;

3) Fluid state: up to gaseous, liquid, or mixed state, especially when the diameter is greater than DN25, it must be distinguished;

4) Fluid viscosity: Usually below 50cSt, it can be freely selected. If it exceeds this value, a high viscosity solenoid valve should be used.

3. Selecting solenoid valves based on pressure parameters: principles and structural types

1) Nominal pressure: This parameter has the same meaning as other general valves and is determined based on the nominal pressure of the pipeline;

2) Work pressure: If the work pressure is low, the principle of direct action or step-by-step direct action must be selected; When the working pressure difference of Z is above 0.04Mpa, direct acting, step-by-step direct acting, and pilot operated can all be selected.

4. Electrical selection: The voltage specifications should preferably be AC220V or DC24, which are more convenient.

5. Choose based on the duration of continuous work: normally closed, normally open, or continuously powered on

1) When the solenoid valve needs to be opened for a long time and the duration exceeds the closing time, the normally open type should be selected;

2) If the opening time is short or the opening and closing time is not long, choose the normally closed type;

3) However, for some working conditions used for safety protection, such as furnace and kiln flame monitoring, the normally open type cannot be selected, and the long-term electrified type should be selected.

6. Select auxiliary functions according to environmental requirements: explosion-proof, check, manual, waterproof fog, water shower, and diving.
