General Purpose High Pressure Solenoid Valve – Normally Closed (GEMYB)

A high pressure solenoid valve is an electromechanical valve that controls the flow of a pressurized gas or liquid. These types of valves can be opened and closed by actuating the solenoid (a coil that creates a magnetic field) when they receive an electrical signal. Thus, you can control or stop the flow in the system. It works with AC and DC electrical energy and provides control of various fluids (air, gas, fuel, steam, water, etc.). There are two- or three-way variants. It consists of body, sleeve, coil, diaphragm and core.

Where is the General Purpose High Pressure Solenoid Valve Used?

High pressure solenoid valves are designed for installations with high line pressure (between 0.5 and 40 bar). It is generally used in industrial automation systems. For example, this type of valve is often used in the chemical, energy, mining and food industries. High pressure solenoid valves provide controllable flow in various plumbing systems. In this way, it is ensured that the liquid or gas flow can be directed and controlled correctly.

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.

General Features

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. 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.
