JET WORKS Check Valve for 3/8 Hose

Jet Works Pro Flow Control Valve for 3/8" ID Hose

Reference: 52-3119

This flow control valve provides improved throttle response and much quicker starts by drying out your water box at low RPM and idle.
Tests showed an average acceleration improvement of 10 feet over an unequipped model in the first 50 feet.
The flow control valve allows unrestricted water flow to the stinger for better top speed, while controlling the amount of water at low speeds for better response. It also allows for easier carburetor adjustment.
The flow control valve does not interfere with normal engine or exhaust pipe cooling and is compatible with all electronic water injection systems.
This model comes preset at 3.5 psi and is adjusted by adding the supplied stainless steel shims to increase spring tension.
Fits all boats equipped with OEM or aftermarket exhaust systems (e.g. Factory Pipe), except Yamahas with OEM exhaust.

Legal racing for all classes.

Main features:
IJSBA legal race
Easily adjustable by rotating the hexagonal part of the valve
Can be installed on any aftermarket exhaust system using the water connection on the stinger
The revised 2015 version allows for lower stall pressure
