Gv. internal - external, 1" FM

Product detailed description

This ball valve is commonly used in residential and commercial buildings for controlling water flow in supply lines and distribution networks. It is designed for installation in systems requiring reliable shut-off and full flow capacity. The extended thread allows for secure connections in tight spaces or where additional reach is needed. Installers should ensure correct alignment of the internal and external threads during fitting to avoid leaks or misalignment.

The valve is suited for applications involving potable water due to its CW617N brass body with nickel plating, which meets ATEST standards. Its operating range accommodates both cold and hot water conditions, making it versatile for use in heating and plumbing circuits. The lever handle provides easy manual actuation in either direction, facilitating quick isolation when required.

Technical parameters

Installation and connection

Ensure the internal (female) and external (male) threads match the corresponding pipe fittings. Apply a sealing compound or PTFE tape to the male thread prior to tightening to prevent leaks. Verify that the lever moves freely and is aligned correctly with the flow direction.

Compatibility and accessories

This valve is compatible with standard copper or plastic piping systems using 1 inch FM fittings. For complete system integrity, ensure all connecting components meet equivalent pressure and temperature ratings. Additional items such as union nuts or sealing tapes may be required depending on the installation method and local regulations.

Technical background for designers

As a full-flow ball valve, it minimises pressure drop within the system by allowing unobstructed passage through the valve body. The CW617N brass alloy offers high resistance to corrosion and mechanical stress, supporting long-term performance in wet environments. The nickel plating enhances surface durability and prevents contamination in potable water systems. System designers should consider the valve’s thermal expansion characteristics and ensure adequate clearance in rigid installations to avoid stress on the valve body.

Service and operation

Regular inspection of the sealing surfaces and lever operation is recommended to maintain functionality. Check for signs of leakage around the threaded connections and ensure the lever moves smoothly without binding. No scheduled service intervals are specified; however, prompt replacement is advised if internal damage or excessive wear is observed.
