Unox Stainless Steel Block Body Normally Closed Solenoid Valve (0–16 BAR)
What is a Stainless Steel Block Body Solenoid Valve?
A stainless steel block body solenoid valve is an electromagnetic valve. It opens and closes by generating a magnetic field, allowing it to control the flow of a fluid from one area to another. The valve consists of a body, sleeve, coil, diaphragm, and plunger.
Where is a Stainless Steel Block Body Solenoid Valve Used?
Stainless steel block body solenoid valves are commonly used in hydraulic and pneumatic systems, which are typically found in machines and equipment to control their movement.
Solenoid valves are manufactured in two types:
-
Normally Closed (NC): The valve is closed when the coil is de-energized and opens when energized.
-
Normally Open (NO): The valve is open when the coil is de-energized and closes when energized.
Normally Closed Solenoid Valve Operation
A normally closed solenoid valve initially allows fluid to pass. When an electric current is applied to the coil, the plunger is pulled upward, opening the orifice. This allows high-pressure fluid to bypass quickly, creating a pressure difference inside the valve. The diaphragm then overcomes the spring force, lifts, and permits fluid flow, opening the valve. All of this occurs very quickly, and the product is designed for optimal efficiency.

Recommendations
-
Mount the solenoid valve with the coil facing upward.
-
Use filters such as strainers upstream of the valve in the system.
-
For high-temperature applications, request high-temperature diaphragm and seal materials when ordering.
Solenoid Valve Selection Guidelines
-
The coil must be compatible with the operating voltage (AC/DC) and protected according to the installation environment.
-
Ensure that the minimum and maximum pressure of the system is considered for valve selection.
-
The nature and temperature of the fluid directly affect valve selection.
-
The flow direction should match the arrow on the valve body during installation.
-
Solenoid valves do not function as check valves, so a separate check valve should be installed downstream to prevent reverse flow.
-
The line where the valve is installed must be free from debris.
