SOLENOID SAFETY GAS VALVES (double action)
Solenoid safety gas valve (double action) is a device designed for control and regulation of gaseous mediums supply in gas burners of hot water and steam boilers, melting and drying furnaces, gas heaters and other gas consuming devices where the multi-step control of the flow is required.
Double action solenoid safety gas valves are composed of two shut-off safety gas valves and additional devices functioning in one housing, which allows combining various functions in one product:
- two shut-off safety gas valves
- shut-off safety gas valve – three-position solenoid safety gas valve (high/low gas flow mode)
- two shut-off safety gas valves and smooth opening function
- two shut-off safety gas valves and gas flow regulator (electromechanical or manual)
- multiblock unit based on the double valve.
ADVANTAGES (as compared with valve block units, assembled with single items):
- smaller overall dimensions (up to 30%);
- low total factor of hydraulic resistance;
- reduced time spent on installation and maintenance.
DIAMETER NOMINAL:
- 15; 20; 25; 32; 40; 50.
OPERATING PRESSURE:
- from 0 up to 6 bar (up to 0,6 Mpa).
CONNECTION TYPE:
- flange;
- coupling.
CLIMATIC VERSIONS:
- -30…+60 °С;
- -45…+60 °С;
- -60…+60 °С.
AMBIENT TEMPERATURE:
- -60…+70 °С (standard);
- -45…+120 °С (upon individual request).
ADDITIONAL FUNCTIONS AND DEVICES:
- can be equipped with position indicators of the shutter, pressure switches, manual or electromechanical flow regulator, density (leak- tightness) control valve;
- for connection of pressure switches, manometers, impulse tubes or other devices and instruments, the holes with G1/4” thread closed with plugs, are provided in the housing.
EXPLOSION PROOF VERSIONS:
- general industrial usage (protection degree IP65);
- explosion proof (protection degree IP67).

LEAK-TIGHTNESS CONTROL UNITS
Leak-tightness control unit is a device designed for automatic checking of the gas valves block units before ignition of the burner and ensures a safe start-up of the boiler.
It is used to control the leak-tightness of the gas train (gas valves block units) of industrial boiler burners and similar gas-burning devices.
HOUSING TYPE:
(fig. 1)
(fig. 2)
Figure 1 – housing version with IP41 protection degree for installation in a cabinet with mounting on a din-rail (СВР-1 series);
Figure 2 – version with IP54 protection degree with the possibility of outdoor installation under roof (СВР-2 series).
FUNCTIONALITY:
- Possibility of time setting for testing the valves in the process of monitoring the leak-tightness of the gas block unit;
- Interacts with various types of boiler control automation;
- Information about the leak-tightness of the solenoid valves is displayed on the LED panel;
- Provides control in manual or automatic modes;
- Can be completed with one or two pressure switches (mechanical or electronic types).
