The spring pressure is adjustable, but the valve can also be pre-set and lead-sealed to order. Maximum pressure 0,1 bar. Use as a non-return valve under vacuum is possible. An inserted riser tube prevents con- tamination by buffer liquid. Where aggressive media are involved, the spring can be covered with inert fluid.
