Piston Type Solenoid Valve – Normally Closed

What is Piston Type Solenoid Valve?

Piston type solenoid valve is an electromechanical valve that acts with the help of magnetic force. It can be opened and closed with the aid of a reciprocating mechanism and is often used to control the passage of liquid or gas. Piston type solenoid valves are often used in industrial automation systems and can change properties such as the speed and direction of the controlled airflow.

Where is Piston Type Solenoid Valve Used?

Piston type solenoid valves are generally used to open or close a liquid or gas flow in a controlled manner. For example, in automatic irrigation systems, irrigation times and amounts can be adjusted by using such valves. In addition, these valves can be used in air or water pressure controlled systems.

Solenoid Valves are manufactured in two types as normally closed (to open the closed valve when the coil receives energy) and normally open (to close the open valve when it receives energy from the coil).

Normally Closed Operation System

Normally Closed Solenoid valve initially allows the passage of fluid. In order for the valve to open, the coil moves with the electric current coming to the coil, pulls the core upwards and opens the mouth of the orifice hole, and thus, the fluid under high pressure advances to the outlet quickly from the bypass hole. With this progress, the pressure inside drops very quickly and a pressure difference occurs inside. Due to this difference, the diaphragm overcomes the spring force and rises upwards and fluid passage is allowed, so the valve is in the open position. All this happens in a very short time. Our product is designed to get the best efficiency.

Suggestions

Mount the solenoid valve so that the coil is up. In the installation, such as a strainer before the solenoid valve, etc. use filters. We use more durable diaphragm and gasket material for high temperatures
Please specify your diaphragm and gasket request for high temperature in your orders.

Things to Consider When Choosing a Solenoid Valve:

• The coil should be selected in accordance with the operating voltage (AC-DC). Protection and insulation should be provided according to the place where it will be applied. (Electricity turns on when air comes in, and turns off again when you cut off the electricity)
• In the line or system you will use, min. and max. pressure values are very important in the selection of the valve.
• The quality and temperature of the fluid is a direct factor in the selection of the valve.
• The direction of the fluid and the arrow mark on the body are in the same direction and attention should be paid to the assembly.
• Since the solenoid valve does not function as a check valve, the fluid flows back at reverse pressures. In these cases, installing a check valve after the solenoid valve is correct for the connection.
• The line to which the valve is attached must be free of impurities.
