EMACO Oblique Landing Valve is a type of hydrant valve used in wet riser and fire hydrant systems. It is a connection point where firefighters can attach hoses and access water for firefighting.

The valve is built in an oblique globe style. This design allows the user to easily connect hoses. The hose connection outlet is a BS336 instantaneous coupling outlet, allowing for quick connection of fire hoses. Oblique landing valves are commonly used as outlets in wet riser systems or external hydrant systems.

The valve is operated using the hand wheel mounted on top of the valve body. Turning the hand wheel lifts the internal stem and seat, allowing water to flow through the valve and into the connected fire hose. Closing the valve lowers the seat and stops the water flow.

Landing valves are a standard part of hydrant and wet riser fire protection systems. They act as the outlet where firefighters connect hoses when using firefighting water supply of a building, premises, or from the municipal’s firefighting water supply.

These valves are commonly installed in locations such as:

Commercial and residential buildings
High-rise buildings and stair landings
Industrial premises
Warehouses and storage buildings
External hydrant systems
Wet riser firefighting systems

They are generally used in charged firefighting standpipe, hydrant or riser systems.

The valve body is made from copper alloy. This provides durability and corrosion resistance, which is important to ensure it operates reliably during an emergency.

What makes the EMACO Oblique Landing Valve different from standard hydrant valves?
The EMACO Oblique Landing Valve features an angled body design that enhances flow efficiency by reducing internal resistance and water hammer effects. Unlike straight-type valves, its oblique pattern delivers smoother, faster discharge under high pressure, making it more effective in high-rise or long-distance hydrant systems.
Can the valve be installed both indoors and outdoors?
Yes. The valve’s gunmetal or copper alloy body offers excellent resistance to corrosion and environmental factors, allowing it to perform reliably in both indoor riser systems and outdoor hydrant points. For coastal or marine environments, it’s especially suitable due to its salt-resistant properties.
How often should the valve be inspected or maintained?
A visual inspection should be performed quarterly, and operational testing (opening/closing under pressure) at least once per year. This ensures the spindle, seat disc, and coupling remain functional and leak-free. Periodic hydrostatic testing at rated pressure verifies long-term reliability.
Is the valve compatible with international hose connections?
Yes. The EMACO Oblique Landing Valve is available with standard BSP or NST threads and can be fitted with instantaneous or threaded couplings as per regional standards (BS, DIN, or NFPA). This ensures full compatibility with existing hose systems worldwide.
What materials are used, and how do they affect performance?
The valve is primarily constructed from gunmetal or copper alloy, providing excellent mechanical strength, corrosion resistance, and sealing reliability. These materials prevent galvanic corrosion and wear, extending operational life in harsh environments.
