The team at BI-TORQ® Valve Automation is proud of our expertise in actuating valves, but we also can provide a full line of manually operated quarter-turn valves as well. Most of our product line comes complete with OSHA-approved locking handles. We also can provide custom oval handles, tandem linkages, spring return "deadman" handles, or overhead levers to suit a variety of applications. Almost all of our manually operated valves have ISO mounting pads, which makes automating the valve simple if either a pneumatic or electric actuator is required at a later date.
