Miniature valves and manifolds

Parker Hannifin has launched a new range of miniature stainless steel needle valves and manifolds for fluid instrumentation applications.

Parker Hannifin has launched a new range of miniature stainless steel needle valves and manifolds for fluid instrumentation applications.

The range operates at up to 414 bar (6000PSI), and offers bubble-tight seating and sealing with lifecycles of over 6000 operations.

The High Performance Miniature range includes 2- and 3-way manifolds for pressure and flow measurement applications, and a needle valve range which can be specified in globe or angled flow patterns. The needle valves are available with a user-specified choice of female or male interfaces, and may additionally be provided with integral single- or double-ferrule CPI or A-LOK compression tube connections. These latter options halve potential leak paths and assembly labour requirements compared with conventional pipe threaded connections.

Valves are fitted with Viton ‘O’ ring. This sealing system features an anti-extrusion back-up ring, plus an anti-blowout design with back seating which minimises atmospheric leakage in the event of a stem seal failure.

The new products are suitable for gas or liquid applications. The space savings are likely to be of particular interest to panel builders, and any other application where space or weight is at a premium, such as on offshore platforms and in portable equipment.

As an example of the savings made possible by Parker’s new range, the body of the 3-way manifold measures 51 x 51 x 27mm (2 x 2 x 1.08 inches). The whole unit, complete with its miniature valve assemblies, weighs just 550g.
