WEIR TYPE 'W' DIAPHRAGM VALVES
KIM Diaphragm Valves are known for their benefits in corrosion and abrasion resistance, offering features of leak tightness and low cost maintenance in severe service applications. The valves are based on simple operating principles and have recently become more widely used by process engineers as a result of the increased range of diaphragms and body lining materials.
KIM Weir Type 'W' Diaphragm Valves are extremely versatile in their application because of the variety of body materials, linings, coatings and grades of diaphragms available. Weir Type diaphragms incorporate the use of PTFE, offering maximum chemical and temperature resistance.
KIM Weir Type Diaphragm Valves manual bonnet assemblies incorporate position indication, and adjustable tamper-proof and over-closure-protection. Over-closure is the most common cause of diaphragm damage, particularly in temperatures over 80° C (175° F). The valves are self-draining when installed at a certain slight angle on the horizontal plane.
KIM unique Over-Closure-Protection is a standard feature on the Type 'N' bonnet. It is adjustable in order to compensate for variations in diaphragm and body lining thickness. The feature is tamper-proof to prevent adjustment by unauthorized personnel.
Pneumatically, hydraulically and electrically operated KIM Weir Type Diaphragm Valves are available for the automatic control of process plants. The actuators can be fitted with many forms of positioners, micro and proximity switches and many other options offering the user, unique cost effective process control of corrosive services.
