Three-position solenoid safety gas valve is a device designed for remote control of flow of non-aggressive gaseous mediums in three different modes:
Three-position solenoid safety gas valves are applied at automated systems of gradual gas flow control.
Such valves combine shut-off (cut-off) unit with manual gas flow regulator and unit of average (intermediate) gas flow in one housing. This design ensures gradual gas flow control as well as manual adjustment of average gas flow rate from 10 to 60 %.
Customized valves can be manufactured with two flow regulators that allow to adjust gas flow rate from 10 to 100 %.

HOUSING MATERIAL:
ALUMINUM
STEEL
Valves in aluminum housings are applied at thermal power facilities (boiler houses, furnace rooms etc.), and also by manufacturers of gas equipment (modular boiler houses, boilers, burners, furnaces, flare facility etc). Low weight, cost and small dimensions make valves in aluminum housings practical in application.
Valves in steel housing are applied primarily at large power plants (heat and thermal power plants, condensation power plants etc). Steel housings are highly resistant to static and dynamic loads due to requirements of equipment application at large power plants.

EXPLOSION PROOF VERSION:
General purpose industrial version of valves is applied at all gas facilities, where there are no special requirements for ensuring explosion safety of electrical equipment.
Explosion proof version of valves is applied at the facilities and premises with special protective measures requirements upon designing, manufacturing and operating of electrical plants.

Motorized gas valve is designed as regulating device and is intended for usage in automatic remote-control systems of gas burning installations to control and safeguard streams of various gas mediums including natural gas, hydro-carbonated gases, gaseous phases of liquefied gas, compressed air and other non-aggressive gases.
Note! Motorized valve is not a shut-off device. It is designed and applied for smooth regulation of gas flow.
OPERATING PRESSURE
HOUSING VERSIONS (two types):
Type 1. Motorized regulating gas valve – a rotary cylinder serves as a working (regulating) member that provides the smooth change of the gas volume flow rate from 0.05% (in a closed position) up to 100% (in a fully opened position).

Type 2. Butterfly-type-gas valve – a rotary throttle serves as a working (regulating) member that provides the smooth change of the gas volume flow rate from 0.5% (in a closed position) up to 100% (in a fully opened position).

OPERATION MODE:
Power drive type
Manual type
In power drive type models, the flow rate control of the amount of passing gas through the motorized gas valve is controlled by the following types of actuators:
In manual type models, the flow rate control of the amount of passing gas is controlled by turning the control handle attached to the output end of the shaft. The scale shows: opening angle in degrees, arrows and signs "+" and "-". When turning the control handle towards the "+" sign, the amount of passing gas increases; when turning towards the "-" sign, the gas flow decreases.
The extreme control of handle positions, corresponding to the minimum and maximum gas flow rates, are limited by stops.
During operation, if necessary, the control handle can be dismantled and reinstalled.
REGULATION MODE (for power drive type models):
Proportional regulation. The following actuators are applied:

VERSIONS:
General industrial usage
Explosion proof
Products in general industrial usage version are applied at all gas facilities where there are no special requirements to ensure the explosion safety of the electrical equipment;
Explosion-proof fitting units are applied at facilities and rooms where there are or may be formed explosive mixtures in the amount that requires special protection measures of the design, manufacture and operation of the electrical installations. To ensure safety in these zones the explosion-proof electrical equipment should be used.
Explosion-proof electrical equipment is the electrical equipment with such a construction as to eliminate the ignition of the surrounding explosive environment due to the operation of this electrical equipment.
