About the product
Safety heads are overpressure safety devices which can be used for almost all pressures in our range. The advantages are a relatively low price, a small size and a delay-free response.
The disadvantages in contrast to pressure relief valves are that the burst pressure must be at least 30% above the operating pressure. In systems requiring acceptance, the permissible operating pressure must correspond to the burst pressure of the system. This entails considerable additional costs. A new safety head must be inserted after each response. Even at normal operating pressure, the safety heads can burst after some time due to fatigue. We have therefore endeavoured to manufacture pressure relief valves at costs in the order of magnitude of safety heads.
