        Main Types of Steam Boiler Valves or Safety Valves

        Gate valve is a sliding type of Boiler valve. In the gate valve the closure membrane is a metal gate. These gates slide down to close the valve. The flow area is equal to the area of the pipe in fully open condition which results in negligible pressure drop across the valve. These valves are usually used in on/off condition.
