Solenoid valves are used in various industries. Due to the versatility of the valve. Proportional valve solenoids can be used with liquids or gasses. making it popular with many manufacturers. The air-operated hydraulic valve uses an electromagnetic field to open and close the valve. This makes the valve a reliable choice for pneumatic and hydraulic systems.

Production Process:

The manufacturer manufactures proportional valve solenoid with a variety of processes, such as CNC machining, and laser welding. injection molding and winding When the valve parts are assembled they are put together

These components include proportional valve solenoid Spool, Valve, Inlet, Outlet, Spring, Aperture, and Actuator. Often the solenoid has a seal.


Manufacturers offer a wide variety of materials for use in the construction of proportional valve solenoids. The pinch valve pneumatic can be made from plastic and metal materials, including PVC, natural polypropylene, PTFE, CPVC, stainless steel, bronze, aluminum, and brass. Seals such as Viton seals or nbr seals are usually made of rubber. Sometimes manufacturers will make seals out of stainless steel.

Design and Customization:

Proportional valve solenoid manufacturers make selections according to application requirements, such as natural fluids/gasses within the pipeline (corrosive, hazardous, viscosity, acidity, etc.), environment, and frequency of pipeline to be used. According to the requirements, they can choose design aspects such as valve size. Valve material, valve type, and configuration. and number of ports

Vendors can customize their proportional valve solenoid system in various ways. For example, a valve is typically construct with two connection areas and one orifice. But you can also make a valve with three connection areas and two openings. Although these valves are often designe to work with a 12V DC power supply, the valves can be customize to work with a 3V, 6V, or 24V power supply. Learn about specific details such as the level pressure, spring return, valve size, etc.

What are the advantages of a pinch pneumatic valve?

Proportional valve solenoids have many advantages. Solenoid valves have been designe and improved over the years. This makes the valve safer and more efficient. The valve can be adjust and install in many positions. This makes the valve versatile and adaptable to a wide range of applications. In its handiest form, the valve can also additionally include of a duration of elastomer tube prepared with a mechanism of pinch bar, supplying a closure for you to prevent and save you from over-pinching of the tube. The pinching mechanism is normally executed via way of means of a molded rubber tube this is located inner a body.

Lippard’s NPP Series 2-Way pneumatic pinch valves are air-piloted gadgets designed to open or near tubes for controlling go with the drift of drinks and gases. Other valve sorts have inner passages which could purpose small quantities of fluid to stay withinside the valve.

Another advantage is the closing and opening operation of the valve. The valve can be open and closed in less than a second. All this is through an automated control system. This is especially important when dealing with high-maintenance toxic glasses and liquids. This makes solenoid pinch valves a viable option within a wide range of processes and applications.


The solenoid valve works with two main components: the solenoid coil and the valve. A coil is a magnetic coil that comes to life from a series of charges and releases a current. This current creates a magnetic field that mechanically converts electrical energy to move the actuator. The actuator is an extension of the valve. This, together with the attached cable, has the function of moving the valve from the open position to the closed position.

Solenoid valves are usually built as a normal close (NC) or normally open (NO) device. Normally closed valves are operated with a rod or piston pin inside. called a piston which is attached to the solenoid coil which will block the flow of electricity. In order to stimulate the flow in the NC valve, an electromagnetic charge must be transmit through the coil. This lifts the piston out of the way to allow flow. On the other hand, there are no valves. Instead, they close when the solenoid is activate.
