AR-YCD21F flanged non-directly operated solenoid valve with diaphragm is designed to control the flow of the working medium in the pipeline
Peculiarities:
- Protection of the pipeline against water hammer due to the special design of the valve
- Used only on systems with pressure from 0.03 MPa
- Maximum pressure up to 3 MPa
Principle of operation and scope:
A normally closed solenoid valve is a solenoid valve that maintains its closed position when no control voltage is applied to its inductive coil. When voltage is applied to the coil, the normally closed valve opens and allows the flow of the working medium through it. When the control voltage is turned off, this valve closes automatically and shuts off the flow of the working medium in the pipeline. If the control voltage wire is broken, the valve will be closed.
In most cases, it is suitable for operation in water supply, heat supply, ventilation and pneumatic control systems. The use of this type of valve is especially relevant when the valve must be closed most of the time or when it must be closed when the power supply to the system is turned off.
Deciphering the designation:
AR-YCD21F - valve model.
80F - nominal diameter in mm.
3 - thread size in inches.
X - connection: F - flanged.
Y - body material: H - cast iron.
Z – sealing material: E – EPDM.
