The slide check is the perfect add on to any remote system!!! When the valve sleeve is full forward, gas is allowed to flow through. When the sleeve is in the rear position, the gas flow through the valve is stopped and gas in the line in front of the valve is allowed to escape. This means that instead of depressurizing your whole remote system you only depressurize your paintgun! The valve has 1/8' pipe threaded hoses at both ends.
