Oblique landing valves are specialized components used in firefighting systems. They are typically installed at specific locations within buildings or structures to provide firefighters with access to water for firefighting purposes. These valves are angled (oblique) in design, which facilitates easier connection of firefighting hoses during emergencies. They serve as an interface between the building's internal plumbing system and the external firefighting hose lines. When not in use, oblique landing valves remain closed to maintain the integrity of the building's water supply system. They are robustly constructed to withstand high water pressures and adverse environmental conditions, ensuring reliable performance during critical situations.
Oblique Screw Landing Vavles are manufactured to BS5041.The landing vavles are classified under low pressure and are suitable for use at nominal inlet pressure up to 16 bar.

Components Of Oblique type wet landing valve
Body
The main structure of the valve, typically made of durable materials like brass or bronze, designed to withstand high pressure and harsh environmental conditions.
Handwheel
Used to manually open or close the valve. Turning the handwheel controls the movement of the valve stem and, consequently, the flow of water.
Stem
A threaded rod connected to the handwheel. When the handwheel is turned, the stem moves up or down to open or close the valve.
Bonnet
The component that covers the stem and the internal mechanism of the valve. It provides a seal to prevent leaks and protects the internal parts.
Seat
The part of the valve body where the disc rests when the valve is closed, ensuring a tight seal to prevent water from flowing.
Disc
Attached to the end of the stem, the disc moves up and down to open or close the valve by making or breaking the seal with the seat.
Inlet and Outlet Ports
These are the openings through which water enters and exits the valve. The inlet is connected to the water supply, and the outlet connects to the firefighting hose.
Pressure Regulating Mechanism (for OPRV)
In pressure-regulating oblique landing valves, this mechanism adjusts the water pressure to a preset level, ensuring consistent output.
Material Of Oblique Landing Valve
Brass
Properties: Corrosion-resistant, durable, and capable of withstanding high pressures and temperatures.
Application: Often used for both the body and internal components due to its reliability and longevity.
Bronze
Properties: Similar to brass, bronze is highly resistant to corrosion and offers excellent strength and durability.
Application: Commonly used for the valve body and moving parts to ensure smooth operation and long service life.
Rubber or Synthetic Seals
Properties: Provide tight sealing and are resistant to wear, chemicals, and extreme temperatures.
Application: Used for the sealing components within the valve to ensure leak-free operation.
