Hand lever valves belong to the product family of robust, manually operated valves used in harsh environments, for metal design in foundries, welding shops, etc., but also in the food processing industry.
Great emphasis was placed on the ergonomic design of the switch, so that it can be easily operated with three fingers. Greater forces can be easily overcome. When used as a main pneumatic switch, the hand lever valve can be locked. The blue knob is integrated into the design and has a contrasting colour. When pressed down, the switch is locked and can be secured with a commercially available lock.
