The TIAL QRJ Boost Control Valve

New for 2014 - Designed with the needs of high performance recirculating systems in mind. The QRJ features a new body design, compact installation envelope, high-flow capacity, and configurable inlet and outlet ports. Ideal for both turbo-charged and super-charged applications.

The body and all internal components are CNC-machined from 6061 aluminum alloy. It features a large 1.50 in (38.5mm) valve and optional configurations of hose and/or v-band connections for the inlet and outlet ports. The valve seat seal utilizes a Viton O-ring that is clamped in place to prevent the possibility of sticking to the seat and pulling out. The valve stem and guide are Teflon-lubricated, hard anodize-coated for wear resistance. The QRJ features TiAL's high performance, long cycle life, zero leakage, and zero breakaway friction for fast and reliable boost control.

The QRJ comes with the traditional machined aluminum banjo-type air fitting and bolt, with an over sized 10mm hose barb for quick actuator response. Color anodized aluminum options in standard TiAL colors of Black, Silver, Red, Blue, Purple. Internal return spring pressure tuned for fastest response. Custom spring options are available for other configurations.
