The adjustable pressure relief valve was originally designed as a safety device to offer a degree of control near heat exchangers. The valve has proved particularly useful when used in systems with flow restricting valves such as plug cocks and non return valves and also pressure inducing plant such as homogenisers and positive displacement pumps.
The valve is particularly useful in applications where an exact pressure must be maintained using electronic equipment, where the valve remains independent to the electronics and prevents any overloading pressure build up.
The standard pressure rating is adjustable between 0 – 5 Bar, however 7 bar and 12 Bar is possible with additional springs.
The valve is manufactured with 316L stainless steel wetted parts and we would recommend the use of a soft seal such as Silicone or EPDM, in preference to PTFE.
Where CIP is to be carried out near the valves upper pressure limit, we would recommend that a pressure relief valve with a manual override handle is considered.
