Asahi/America Type 14 Diaphragm Valves offer many combinations of body materials and elastomeric diaphragm materials. This valve is designed to resist abrasion and clogging. The path of the fluid has a smooth, streamlined flow. Slurries at low pressure that would normally clog most other valve designs easily pass thru this type of valve. Asahi/America Type 14 Diaphragm Valves are ideally suited for throttling as well as ON/OFF service in applications ranging from water treatment to chemical abrasion processes.
• Position indicator standard • 150 psi maximum @ 70°F • Adjustable travel stop • Pipe connections - socket, threaded or flanged • Weir design allows for throttling • Automation with no body modifications
• Diaphragms available in FKM and Nitrile • PVDF gas barrier on PTFE models • Pneumatic actuators • Stem extensions • Limit switches • Square operating nuts
Georg Fischer Type 514 PVC and CPVC Diaphragm Valves are ideally suited for throttling applications for most fluids including abrasive solutions and slurries. Type 514 PVC and CPVC Diaphragm Valves are supplied with true union socket end connections, allowing the valve to be removed from the process without the need for additional fittings. Georg Fischer Type 514 is manufactured with an internal weir with a self-flushing design.
• Type 514 valves are supplied with socket end connections only • Elimination of bolts removes corrosive weak point • Visual position indicator on valve handle • Increased pressure rating of 240 psi @ 70°F on most valves • Increased Cv values of 2 to 3 times competitive designs
This full-featured valve is engineered to provide accurate throttling control and shut-off for industrial, chemical and water treatment applications, as well as the handling of liquids with suspended solids, viscous fluids and slurries. Weir-type design utilizes a choice of elastomeric diaphragms with non-rising stem and built-in position indicator. Strong buttress thread, true union style end connection allows ease of installation and service. Available in IPS sizes 1/2” through 2” with socket and threaded end connectors. Heavy-bodied Schedule 80 PVC or CPVC smooth-wall construction provides extra strength, superior chemical and corrosion resistance while maximizing fluid flow. Choice of high-grade, abrasion-resistant EPDM, Viton® or elastomer-backed PTFE-laminated diaphragm allows application specific selection for optimum chemical resistance.
• 235 psi @ 73°F (for complete size range) • Built-in mounting holes for self-tapping screws • Rugged construction with strong buttress threads • Available with EPDM, Viton® or PTFE diaphragm • Dual end connectors (socket and thread) on PVC and CPVC • SR threaded ends - SS-reinforced threaded end connectors
