D & T Series: Bi-directional

DL & TL Series: Uni-directional

High Cycle, Zero Leak Ball Valve

Hoke’s DL/TL ball valves are uni-directional, high cycle valves that exceed 100,000 cycles with zero seat leakage.** 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. 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.
