• The DK manual handwheel and bonnet are totally waterproof, which means that all internal metal components are isolated from the external environment The manual handwheel and bonnet are made with glass-filled polypropylene (GFPP), which provides high mechanical strength and corrosion resistance A floating pin connection between the control screw and diaphragm evenly distributes the compressive load on the diaphragm and results in an improved seal The new mounting plate allows the DK diaphragm valve to be anchored to a wall or panel. It also facilitates axial alignment of the valve with the rest of the piping system

This Normally Closed Pneumatic PP valve is made with an PTFE diaphragm and True Union Sockets to create a removable connection to your piping system. Able to be mounted in any position, the DK is ideal solution for modulating flow in either very clean or abrasive slurry applications. The new innovative and patented Dialock locking mechanism allows the manual handwheel to be adjusted and locked in over 300 positions. The re-designed weirstyle body has significantly improved the DKs flow rate compared to the old design and it facilitates precise linear flow regulation through the valves full range of operation.
