Hygienic Inclined Seat Valves LCV Type Y

RIEGER LCV Single seat valves are found in the plants of food industries. They combine the advantages of the dead leg free valve body with the concept of the maintenancefree welded pneumatic actuator. The spring-loaded actuator can be used as spring-closing as well as spring opening by easy turning.

Right angle and change-over valves base on the same bodies. The can be combined on the many ways and so diminish the spare part costs. In daily use, the LCV valves grant high flexibility inside the system and the perfect application for your liquid products.
