PLAST-O-MATIC makes two types of Pressure Relief Valve, the RVT and the RVD/RVDM.
The RVT is an angle pattern design featuring a non-sticking solid PTFE shaft passing through three U-Cup seals. Venting between the upper and centre U-Cups results in the patented FAIL-DRY design for added protection. If the two lower U-Cups seals fail, fluid weeps through a vent port indicating maintenance should be carried out. In the meantime the third seal continues to protect the control spring.
The RVD is an angle pattern design featuring a single diaphragm which is an advantage where crystallisation problems can cause valve sticking.
The RVDM is an in-line pattern design.
