Pressure Reducing Valve has been designed to meet the needs of modern fire protection technology. It enables a uniform firefighting pressure to be maintained at any hydrant in a fire protection system irrespective of its location. Efficient pressure control is not affected by differences in inlet pressure that may occur at varying flow levels.
Expensive relief piping systems are completely eliminated, thus dramatically reducing installation costs. The regulator can be quickly and easily adjusted in-site to meet individual floor level pressure requirements.

SD-P1 Pressure Gauge are specifically designed for Fire Sprinkler Services. The pressure gauge is UL Listed and FM approved. It has corrosion resistant polished stainless steel case and Bezel and Brass wetted parts. The dial has pressure reading in KG/ SQCM and PSI. The gauge window is hardened glass.
The pressure gauge must be mounted by square provided for spanner grip on the socket and not by turning the case. Turning of case will damage the gauge. Use PTFE tape around male threads of the gauge for sealing. Pressure gauge must be mounted in vertical position and isolated with valve or cock. The pressure gauge must be handled with due care for best results, the gauge should be stored in the original packing in which it has been shipped. It is advisable to ship the gauge in the same package for future transit.
The pressure gauge, which is visibly damaged, should not be installed. It is recommended that the pressure gauges must be inspected regularly for possible corrosion or damage. The gauge must be periodically calibrated as per requirement or as per local authority having jurisdiction.
The construction of the NAFFCO Air Release Valve has been designed with stainless steel trim to give years of smooth operation. The Air Release Valve should be mounted at the high points in a piping system to automatically remove pockets of air as they accumulate.
The valve can also be used to slowly release air in pump casings. This valve continuously eliminates air from a system by releasing small quantities of air before huge air pockets can happen.
When continuous accumulations of air in the pipeline occurs (lacking air release valves) this causes the flow capacity to slowly decrease hence power consumption also slowly increases which is unnoticeable at first, until flow drops dramatically, which can even lead to complete stop of the flow due to large quantity of air.
Another problem resulting from excessive air accumulation is un-explained pipeline rupture. These ruptures are passed off as the result of ground settling or defective pipe, where as in reality its large air pockets greatly increase pressure surges (normally occurring) when flow stops and starts causing the rupture.
VALVE OPERATION
The NAFFCO Air Release Valve, as got, is a typically open valve and will gradually vent air through the orifice. As liquid enters the valve, the float will rise, consequently shutting the opening. As air aggregates in the piping system and enters the valve, the float drops enabling the air to be vented out through the opening.
The lever component gives mechanical advantage to the orifice. Amid system operation, the pipeline pressure applies a solid upward drive on the sealing com- ponent, the orifice button.
The lever instrument amplifies the heaviness of the float with the goal that the hole will open under high pipeline pressures. Extra ports are accommodated flushing, testing and draining purposes. This cycle automatically repeats as air accumulates inside the air release valve, thereby preventing the formation of air pockets.

A ball valve is a simple yet efficient quarter-turn valve that controls flow using a hollow, rotating ball. When the ball’s opening aligns with the pipe, fluid or gas flows freely. A quick 90-degree turn shuts off the flow completely by blocking the passage. The attached handle provides clear visual confirmation—parallel to the pipe means open, while perpendicular means closed. This straightforward design ensures reliable operation, making ball valves a popular choice for quick shut-off applications in plumbing, industrial systems, and gas lines. Their durability and ease of use make them ideal for both manual and automated flow control.
