Technical overview
RIV 250 Opale is a spring operated pressure relief valve designed for low-pressure protection with an environmentally safer discharge method. The inlet is a 1-1/2" ISO 228/1 BSPP Thread, while the outlet is a hose connection with 45 mm hose diameter, allowing you to connect a hose/pipe and direct any vented leakages into a proper tank. The relief setting is adjustable from 0.5 to 1.5 bar (7–21 psi), and the valve is rated for 1.5 bar (21 psi) working pressure in this range. Construction includes a brass body with FKM sealing for durability in demanding service conditions.
