Rotex solenoid valve Engineered Valves MANUAL RESET SOLENOID VALVE

 

Manual Reset Solenoid Valves are used in applications and processes demanding utmost safety checks before starting / stopping the process.In all such application, human intervention is the final check before the process is taken into/ taken off the auto mode.

Based on the nature of the process, the solenoid valves are required to stop the process from starting automatically in case of an emergency or vice versa. These valves are called Manual Reset valves with Latching on Energization. They are also referred to as no voltage Release or Free handle type Manual reset.

ROTEX offers this series of valves in three constructions :

Manual Reset, Latching ON Energization :

Manual Reset, where in the Manual Reset button is used to compliment the power supply provided to the solenoid. On pressing the Manual Reset button, the plunger is lifted and latched electrically. The Valve trips when the power to the solenoid valve is removed.

With this feature, ROTEX offers a comprehensive range of Manual Reset solenoid valves in 2 Port, 3 Port and 5 Port constructions.

Manual Reset Tamper Proof :

Where in the valve cannot be operated till either by pressing manual reset button or by providing electrical supply. The valve changes position only when the electrical supply is provided and button pressed momentarily. On de energizing the solenoid, the valve trips.

This feature is currently available in 3 port valve only.

Manual Reset, Latching on De-energization :

In certain application, the valves are energized on automatically, however they are required to remain energized till manually turned off. These valves are called Manual Reset with Latching on De-energization of the Solenoid. They are also referred to as Trip shut off type Manual Reset Valves. Solenoid Valves used in Fire Fighting systems are typical example of application of this type.

FEATURES OF MANUAL RESET SOLENOID VALVE :

• Wide range of 2, 3 and 5 ports are available.
• Without power to the solenoid, pressing of manual override actuates the valve and releasing resets the valve
• Even when power is supplied to the solenoids, the valve does not actuate till set by pressing manual override. The valve reset when power to the solenoid is cut off.

APPLICATION :

Manual Reset ON (Latching on energization) valves are to be used for applications which demands utmost safety check before starting of the process. Valve cannot be operated electrically.
The valve switches ON when electrical supply to the solenoid is available followed by manual operation. In absence of power to the solenoid, the valve can be operated manually.
The valve is switched OFF when power to the solenoid is removed.

Some of the examples where Manual reset ON valve should be used, are starting of Fuel gas flow, switching on solenoid valve for starting main process, etc.
