TORK has been manufacturing industrial control valves since 1985. The company has been operating in the Czech market for 20 years and has many satisfied customers. BOLA spol s.r.o. is the exclusive representative. TORK products are sold in 87 countries worldwide and meet the strictest certification requirements, finding applications in the following industrial sectors:
When the solenoid coil is energized, it becomes an electromagnet and generates magnetic force. This force enables the movement of the core inside the valve. In this way, the valve opens and closes. If the fluid does not pass through the valve without voltage, it is an NC (normally closed) system. If the fluid passes through the valve without voltage, it is an NO (normally open) system.

If the coil is energized, the opening through which the fluid flows is normally closed or normally open.

When selecting a solenoid valve, the following parameters should be considered:
Differential Pressure
When selecting a solenoid valve, it is essential to determine whether the fluid pressure corresponds to the valve's operating pressure. Incorrect determination of operating or differential pressure can lead to malfunction or defects in the valve. For the proper functioning of an indirectly operated solenoid valve, a differential pressure of at least 0.5 bar is usually required. Directly operated solenoid valves operate regardless of external pressure. This information is indicated on the coil label of TORK solenoid valves.
Temperature
The temperature of the fluid passing through the valve is important. Incorrect values can lead to failure of the present sealing elements.
Valve Body Material
Valves are most commonly made of brass. Stainless steel is used for internal components. The material used varies according to the area of application. For example, valves for aggressive environments are made of PTFE-coated brass, and valves for use in the food industry are made of anodized aluminium.
Coil Operating Voltage
Incorrectly selected coil voltage negatively affects the valve's operation. Our range includes valves with power supply: 110 VAC, 12 VAC, 12 VDC, 230 VAC, 24 VAC, and 24 VDC.
Solenoid Valve Connection Size
When selecting the right valve, you should also focus on its size (connection dimension).
Like differential pressure, this information is indicated on the coil label.

Type of Fluid and Position of the Solenoid Valve
Solenoid valves are suitable exclusively for regulating clean fluids. They are not used in applications where fluid with particles flows. These can adhere to the sealing element and disrupt the valve's operation. Another problem is fluid containing calcium. Lime particles can block the inside of the valve over time, limiting its proper operation.
Furthermore, it is necessary to select the valve according to the type of medium that will pass through it.
We offer valves for:
The valves have official certification for use with drinking water. They are safe and non-toxic. The valve body is made of brass, and the internal components are made of stainless steel. We recommend installing a filter before the valves to capture unwanted impurities. The condition for this valve is installation with the coil positioned on top.
These are solenoid valves for heating water, mineral oils, neutral gases, and for air distribution and regulation.
e-shop: Solenoid Valves for Water
Solenoid valves for hot water and steam are available in NC, NO variants. They are designed for operation with an operating temperature of up to 160 °C. Installation with the coil positioned on top is strictly required.
e-shop: Solenoid Valves for Steam
The valve is used for water and aggressive environments. Immersion is possible up to 10 m for 72 hours. The valve body is made of PTFE-coated brass, and the internal parts are made of stainless steel. The cable is 3m long.
e-shop: Solenoid Valves for Use in Aggressive Environments
We also offer solenoid valves for use in the food industry, in explosive environments, for air conditioning units, for heating oil, and more.
