NAFFCO pressure reducing oblique landing valves are suitable for installation on wet risers in buildings for fire fighting purposes, permanently charged with water from a pressurised supply. These landing valves are pressure reducing type designed to provide a range of outlet pressure (bar -bar). The PRVs we proudly produce are perfect for workplaces with heavy-duty machines, especially oil rigs, marine vessels , chemical plants, and buildings (rising mains).

The function of PRVs is to regulate the outlet pressure within certain range regardless of how high the inlet pressure is.

They are found almost every for example under public roads, in large buildings, in Tunnels, on Chemical plants, onshore and offshore platforms,. You can benefit from our top notch. It can accommodate Straight Through Type, Oblique Type, Right Angle Type, Bib Nose Type, Pressure Regulating ‘E’ Type and even Wedge Type Valves.

FIRE HYDRANT ( LANDING ) VALVES : Fire Hydrant Valves System is an effective and efficient means of extinguishing large fires, Hydrant system enables the fire fighter to attack the seat of the fire from a distance.

Fire hydrant valves are important source of water which is crucial for fighting fires on any level of your building. They can be used in multi-story buildings where a fire fighting system should be available for fire brigade use. The globe pattern is the most reliable and acceptable valve to service in wet piping system, the primary function of hose valve with angle type to control the water at the hose station. Description Description Fire hydrant landing valve is one of the most important fire-fighting equipments. It can be fixed in factory, warehouse, building and public places.

It can also used for ferry fire with fire hoses and fire nozzles. The sign also shall identify the location of the addi- Additionally, the requirements for sprinkler system.

The unloading valve accomplishes this task.

An accumulator provides pressure to the actuator (cylinder in Fig. 5) at the moment the directional control valve is shifted. Pressure does not have to build from a low pressure as it does in a circuit with a open-center directional control valve. They are used for discharging fire retardants and are used to control the fire in an efficient manner. Landing Valve cabinets are used to keep the landing valves protected.

These valves are made using quality approved material keeping in mind the safety norms defined by the local government.

We assure our customers that the presented hydrant landing valves are quality examined on quality parameters, in order to meet the customer’s requirements.
