Safety Valve

Exceed is known as the leading valve brand in Safety Valves. We manufacture all kinds of Industrial Valves like Globe Valve, Gate Valve, Swing Check Valves, Strainers, Ball Valves, Safety Valves and NRV's.

The function of the Safety Valve is to protect life and property against failure to control system pressures, ie it offers the last means of reducing system pressure before total failure. A safety valve can be considered as a pressure reducing or pressure removing device. When there is any excessive internal fluid pressure then this valve would open so that the damage in the system can be prevented. These valves are commonly used in gas and steam lines
