High Cycle, Zero Leak Ball Valves – D, DL, T, TL Series
For remote actuation , factory-assembled Hoke Space Saver™ Actuators are available. D, DL, T and TL series valves can be ordered with welded end fittings to prevent accidental disassembly or with gasketed end fittings, if valve rebuild becomes necessary.
Hoke’s DL/TL ball valves are uni-directional, high cycle valves that exceed 100,000 cycles with zero seat leakage. Depending on seat, seal, and washer material selected.|For remote actuation , factory-assembled Hoke Space Saver™ Actuators are available. D, DL, T and TL series valves can be ordered with welded end fittings to prevent accidental disassembly or with gasketed end fittings, if valve rebuild becomes necessary.
In applications where bi-directional flow is required, Hoke D and T series valves exceed 50,000 cycles. Hoke ball valves can be ordered in brass, 316 stainless steel or Monel® materials with a manual handle as standard.
