Schrader Bellows K022-090 Sub Base

The Parker Schrader Bellows K022090 Sub Base is a base-mounted manifold component for the Valvair II series that provides a dedicated platform to mount pneumatic valves with 3/8" NPT ports. Designed for a 5-port, 4-way configuration with side-port connections, it uses 3/8" NPT for valve and exhaust ports and delivers a coefficient of volume (Cv) of 4.8, suitable for a range of industrial pneumatic circuits. It supports operating pressures from 35 to 140 psi and temperatures from 0 to 125 °F, and its overall dimensions are 7 9/16" in length, 2 7/8" in width, and 1 3/4" in height, making it a compact base for modular valve assemblies. The subbase is intended to simplify maintenance by allowing valves to be swapped without disturbing piping or wiring, and it is supplied as part of a kit that includes a subplate, bolts, and gasket for straightforward installation. As part of the Valvair II family, the K022090 Sub Base serves as a core element of pneumatic control manifolds where multiple valves are mounted on a single base to create flexible, scalable control architectures.
