This line of manifold inert solenoid pumps and valves has a footprint as small as 0.5 in. for space-saving mounting. A highly efficient threaded collar design is employed to secure the valve or pump to the manifold. The locked-in threaded mounting collar is hand tightened into the manifold port to ensure an even load on the gasket seal for pressures up to 100 PSI. By positioning the pump or valve closer to the point of fluid introduction, the screw-in manifold design minimizes internal volume.
