Sanitary Diaphragm Valves


Our range of sanitary diaphragm valves is designed and manufactured to meet or exceed the stringent requirements of industry standards including those set-forth in BPE. All Bio-Rx and Bio-Guard bodies are forged in 316L grade stainless steel in accordance with ASTM A182 S9 specifications, providing the highest degree of integrity, strength, sur-face finish, and levels of purity. Distinctive features clearly provide an added benefit for the user and raises the bar in setting a higher industry standard.

° Uniform wall thickness allows for porting in any orientation
° Broader weir profile minimizes diaphragm deformation
° Integral end-connections allow maximum cutback to facilitate orbital welding and system integrity
° Low sulphur content improves welding integrity
° Low ferrite content eliminates concerns for contamination or rouging
° Complete material traceability to support validation
° Comprehensive marking to BPE, identifies heat numbers, drain angles, surface finish code, size







Where life, performance, and reliability are essential to the success of your product and process, our diaphragm, developed and manufactured utilizing the most advanced compounding and molding techniques, provides the desired assurances cost effectively. An extensive range of approved elastomer and flouropolymer products address and resolve the performance criteria related to your specific applications.
