Description
The ABS Metric Dialock Diaphragm Valve is a high-performance shut-off and control valve designed for demanding metric ABS pipework systems. Featuring a robust ABS body, EPDM diaphragm and the patented Dialock handle, this valve delivers precise flow control, excellent sealing performance and long-term reliability.
Diaphragm valves are particularly well suited to applications where contamination, aggressive fluids or frequent operation are a concern. The valve isolates the operating mechanism from the process fluid, reducing wear and helping to maintain system integrity over time.
The standout feature of this valve is the Dialock handle, which provides positive, controlled closing with a clear mechanical stop. This prevents over-tightening, protects the diaphragm, and ensures consistent shut-off every time. The handle also improves operator ergonomics, making the valve easy to use even in frequent or critical service conditions.
Union end connections allow the valve to be removed easily for inspection or maintenance without cutting the pipework. Metric plain ends are designed for secure solvent welding using ABS solvent cement and cleaner, ensuring full compatibility with ABS metric pipe and fittings.
