The Flamco Prescor safety valve is a diaphragm-type safety device designed for sealed heating systems. If the set pressure is exceeded, it opens and discharges the medium, protecting the boiler, pipework and other components against damage caused by overpressure. The valve features a specially designed opening mechanism for full discharge at the opening pressure and is suitable for water and water/glycol mixtures (up to 50%). The robust brass construction is suitable for long-term operation in standard heating and cooling applications.
