Ball Check Valve | MAXI Check L (MCL)

Supplier: Upwey Valve & Engineering

The Upwey Valve & Engineering range of locally manufactured valves now includes the MAXI-Check L Low Pressure Ball Check Valve.

Price Guide: POA

The large port design prevents clogging while the urethane coated ball is free to move and rotate with the media as it flows through the valve.

This continuous movement prevents scale build up on the ball and within the ball bonnet, which can be inspected through the bonnet blanking flange. The seat is integral to the one piece body.

The valves are fabricated which allows flexibility of manufacture to suit clients requirements. Standard face-to-face measurements are according to AS4794-2001 paragraph 3.2.2 FIG. 3.1 or GENERAL DESCRIPTION DIN 3202-F6.
