Product Category Description:
The SG-900 system is designed to prevent the depletion of gas during testing and to eliminate the downtime required to change empty cylinders. The manifold will automatically switch gas supply from the primary cylinder to a reserve cylinder when the primary supply is depleted. This occurs when the pressure on the primary gauge drops to approximately 160psi. The switch is completed by turning a lever to designate the reserve cylinder as the now operational primary cylinder. The process may be repeated as often as necessary to maintain smooth and uninterupted testing procedures, and cylinder refills can be accomplished without work stoppage.
The manifold is available in chrome plated brass, or stainless steel for corrosive gas applications. All pigtails have a reverse flow check valve to prevent back flow of gas while changing cylinders. The outlet fitting on the delivery regulator is 0.64cm (1/4") NPT female pipe.
Ordering Information: Manifolds include a delivery pressure regulator, wall bracket, and two 61cm (24") pigtails with reverse flow check valves (fasteners not included).
