This widespread, successful application demonstrates their consistent ability to deliver accurate level control, durable construction, and long-term, maintenance-free operation, providing dependable service in diverse environments.
A Long Shank Fill Valve is a specialized float-operated valve designed to automatically control and maintain water levels in tanks and cisterns. Its primary function is to open an inlet when the water level drops, allowing for refilling, and to close once the predetermined level is reached, preventing overflow. The defining "long shank" (extended stem) allows the valve body to be mounted higher on the tank wall while the float and control mechanism operate at a lower level, accommodating deeper tanks or specific installation requirements. This ensures reliable, automated filling in applications ranging from residential toilet cisterns to industrial water storage and cooling systems.
Product Feature and Application
Long Shank Fill Valves feature an elongated inlet stem designed to pass through thick tank walls or decorative cabinetry with ease. Their primary feature is the extra-long threaded shank, which provides a secure, leak-proof connection in specialized installations where standard valves cannot reach. They are widely applied in concealed toilet cisterns, high-end bathroom vanities, and commercial water tanks, ensuring a stable and reliable water supply.

Installation Guidelines
1.Clean and prepare the piping system thoroughly before installing the valve.
2.Before installation, remove any protective end caps and inspect the valve ports and seating surfaces to ensure they are clean.
3.Provide adequate support for the valve to avoid stress from connecting piping.
4.Confirm that the valve’s pressure and temperature ratings are suitable for the intended service conditions.
5.Before placing the valve into service, cycle it fully from open to closed to verify smooth operation.
6.After installation, check that the packing nut is properly tightened.
Operating Instructions
Long Shank Fill Valves are manually operated. Turn the handle counterclockwise to open and clockwise to close.
Inspection and Maintenance
1.Routine inspection and preventive maintenance are generally not required, aside from occasional adjustment of stem packing and periodic cycling of the valve from open to closed.
2.If a packing leak occurs, tighten the packing nut clockwise by about a quarter-turn—or until leakage stops—to increase sealing pressure on the stem packing. Never repack a valve while it is under system pressure.
3.When replacing the valve stem, also replace the packing material.
