Globe valve 15kch888r with solenoid actuator Pn 16

Valve 15kch888r is a diaphragm shut-off valve with an electromagnetic actuator designed to completely shut off flow of the working medium. It is used as a remotely controlled shut-off valve on pipelines transporting fresh water, air, or brine. The operating temperature of the medium varies within the following ranges:

• Fresh water: from +1 to +45 °C.
• Air: from 0 to +45 °C.
• Brine: from -40 to +45 °C.

Design and Operating Principle

The 15kch888r valve is equipped with an electromagnetic actuator (solenoid) that controls the shut-off mechanism without the need for mechanical intervention. The main components of the design include:

1. Body: made of ductile iron.
2. Shut-off mechanism: consists of a spool with a rubber seal and a diaphragm.
3. Electromagnetic actuator: hermetically protected by a plastic housing to prevent moisture exposure.

Operating principle of the valve is as follows:

• In the normal state (without voltage applied), the valve remains closed due to the pressure of the spring and the working medium above the diaphragm.
• When electric current is applied to the solenoid coil, the armature of the electromagnet lifts, opening the relief hole. This reduces the pressure above the diaphragm, causing the shut-off mechanism to move upward and open the passage for the working medium.
• When the voltage is turned off, the armature returns to its original position, the pressure above the diaphragm is restored, and the shut-off mechanism closes the flow again.

For emergency opening of the valve, a special screw is provided to manually lift the spool.

Operating Conditions

To ensure proper operation of the 15kch888r valve, the following conditions must be met:

1. Installation is only possible on a horizontal pipeline with the electromagnetic actuator facing upward. A deviation from the vertical by up to ±15° is allowed.
2. The working medium must flow strictly in the direction of the arrow on the valve body.
3. Before commissioning, trial operations must be conducted to check the tightness and functionality of the device.
