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.
