Total isolation solenoid valves (DRY) combine the traditional characteristics of strength and reliability with construction solutions that make them particularly suitable for the control of aggressive and/or non-contaminable fluids.
The fluid is in contact only with the valve body and the isolation lever or diaphragm; in this way the fluid is protected from any chemical contamination and/or thermic shock
Produced in 2/2 or 3/2 normally closed, open or universal service versions plus miniaturised, silent versions and with a latching actuator.
The numerous versions available, the variety of materials employed and the possibility of studying special solutions make this range of solenoid valves particularly versatile, suitable for applications in the food, a biotechnology, chemical/pharmaceutical and physiological/medical sectors.

Technical details of Type 23:
2/2-Way direct acting solenoid valves
Body: GG-25, GS-C25, Stainless Steel
Sealing: NBR, FKM, EPDM
Connection: flange DN15-DN250
Pressure range: 0-1 bar
Valves of this type switch the sealing element directly via the magnetic systems. In this case the seal usually needs to be lifted against the effective operating pressure from the seat simply by the actuator. A closing spring keeps the valve closed, supported by the pressure of the medium. The function depends on the size of the seat, the effective operating pressure and magnetic power.
Direct acting solenoid valves do not have any pilot orifice. So these valves are less sensitive to any slight pollution of the media.
These valves are ideal for vacuum applications. They operate from 0 bar up to the maximum operating pressure.
Direct acting solenoid valves are used, for example, for:
- Vacuum technology
- Venting of gas and tank systems
- Safety control units for burner control systems
- low pressure gas supply for industrial and domestic applications in accordance with DIN EN 161
Extras for direct acting valves are, for example:
- normally open
- increased pressure range
- position indicator
- ex-position indicator
- explosion proof
- temperature design up to +200°C
- high viscosity media
- special flange ANSI
- NPT-thread
- special voltages
- free of oil and grease
- outdoor application
- free of nonferrous metal |

KOFLOC PV 2900, 2910, 2920, 2930, 2940
The KOFLOC Small Proportional Solenoid Valve MODEL 2900 SERIES (U.S. P.A.F.) allows high-precision control of minute amount of fluids. It also has the lowest hysteresis in the industry, within 15% of full-scale current, making it ideal for automatic gas flow control in analyzers such as gas chromatographs, biomedical and other industrial applications. The annealed magnetic materials together with the specially designed flat spring (P.A.F.) completely eliminate flow fluctuations caused by vibrations due to wobbling plunger core or its frictions. The magnetic yoke of MODEL 2900 SERIES is annealed after machining, not bending, for improved magnetic flux permeability, resulting in greater magnetic force.
FEATURES
- Lowest hysteresis in the industry
- Low power consumption
- Special flat spring (P.A.F.)
- Superior resolution
- PWC (Pulse Width Coding) control possible
APPLICATIONS
- Analytical equipment
- Gas chromatography
- Industrial application requiring precision pressure control |

Solenoid valves from GF Piping Systems play a major role in industrial systems engineering due to their outstanding quality. The comprehensive range with a large number of different versions fully satisfies international standards and customers' requirements.
Their proven advantages and special features make them convincing in operation. Plastic solenoid valves from GF Piping Systems are the ideal products, especially for demanding media. Their good characteristics and short response times make the solenoid valves suitable as components of coordinated control circuits and filling stations.
They are used for diverse functions, e. g. opening, shutting, dosing, dispensing and mixing. The solenoid system and medium area are separated from one another by means of a separating membrane. The valve therefore has a long service life, even with dry runs.

| In most refrigeration applications, in order to automatically control the flow of fluids in a system, it is necessary to be able to start or stop the flow in the refrigerant circuit. An electrically operated solenoid valve is usually used for this purpose. Its basic function is the same as a manually operated shutoff valve, but it can be positioned in remote locations, and may be conveniently controlled by simple electrical switches. Solenoid valves can be operated by a thermostatic switch (the most common in refrigeration systems), float switches, low pressure switches, high pressure switches or any other device used for making or breaking an electric circuit. |
