Diaphragm Valves – 700 Series
Chemline offers manual and actuated diaphragm valves suited to every application, from process sampling and throttling; to rapid cycling applications such as bottling plants; to high-purity food preparation systems; to ultra-high-purity systems that require minimal dead legs; to abrasive services such as heavy slurries and air-entrained powders. Our 700 Series valves feature modular design and interchangeable bodies, diaphragms and actuators which minimizes spare parts requirements. All major parts are solid plastic, corrosion resistant and light weight to minimize stress on plastic piping.
