With the use of the high quality valve and diaphragm control system, the type-RZ was created to be the most reliable Blow off valve system available.
Large 40mm Valve. The CNC machined aluminium valve is coated with a hard anodizing, to withstand extreme friction, maintain an airtight seal and increase durability.
Quick Response. To ensure proper valve movement, a durable, airtight, pressure resistant Bellofram diaphragm is used. The Short valve stroke allows a compact top housing design. This smaller top housing volume also adds improved valve response.
Dual Spring System. A carefully selected spring rate prevents premature discharge under high boost pressure and increases valve speed for quick response application. Adjustable Spring Rate: spring tension can be tuned by the adjustment screw, to suit mass applications.
