Haake Technik HSV - Valve Interlocks


Valves play an important role in many industrial production lines and energy networks. Valves perform essential functions regarding safety and process control systems. The correct setting and operation of valves is crucial for ensuring the operational safety of entire installations.
Haake HSV valve interlock systems provide a fail-safe system for the controlled opening and closing of valves. They are used whenever a specific opening and closing sequence for several valves is involved for the purpose of accident prevention, protection of materials, or guaranteeing process safety. Chains and padlocks do not provide adequate protection against operational error, vandalism or theft. A simple and safe-to-use interlock system guarantees the best possible protection against physical injury and/or damage to assets or the environment.
