PVDF Diaphragm Valve
PVDF Diaphragm Valve Manufacturer
The MVS PVDF Diaphragm Valve is engineered for high-efficiency flow control in highly corrosive and chemically demanding environments. Designed with precision and built using PVDF (Polyvinylidene Fluoride) and Isotactic Polypropylene (PP), this two-way valve offers exceptional corrosion resistance, long-term durability, and smooth performance in both throttling and shut-off applications.
Available in sizes ranging from 15 mm to 150 mm, the valve is manufactured to handle diverse industrial media with ease. Its robust thermoplastic body construction is supported by a wide selection of elastomer diaphragm materials, making it adaptable to many operational conditions and process requirements. Whether your application demands a sulphuric acid resistant diaphragm valve or solutions compatible with bromine, hydrochloric acid, or chlorinated fluids, MVS delivers unmatched reliability.
Built to serve critical operations, our corrosion resistant PVDF diaphragm valves are ideal for use in chlor alkali processing, bromine handling, and other aggressive chemical applications. For processes involving sulfuric acid, these valves ensure safe and leak-free operation, while resisting wear from abrasion and scaling over time.
As a PP diaphragm valve manufacturer and PPH diaphragm valve supplier, MVS brings precision engineering and global supply capability under one trusted brand. Our acid resistant thermoplastic diaphragm valves combine the mechanical strength of polypropylene-based bodies with the chemical shielding of PVDF, creating a valve suitable for a wide variety of harsh environments. MVS also serves as a trusted PVDF diaphragm valves exporter, providing clients worldwide with high-quality, tested, and proven valve systems. Each valve is carefully manufactured to meet international standards for performance, durability, and safety in demanding conditions. From bromine handling plastic diaphragm valves to chlor alkali and sulphuric acid applications, MVS PVDF diaphragm valves offer the performance and reliability your process demands.

What is a PVDF diaphragm valve and how does it work?
A weir type diaphragm valve with a single piece moulded thermoplastic body and a soft seat. The handwheel drives a compressor that presses the diaphragm onto the weir to close the line. The body carries reinforcing ribs, and the inverted diaphragm design reduces stress on the diaphragm — two details that matter more on a plastic body than a metal one, because thermoplastic creeps under sustained load.
Which body and diaphragm materials are available?
Body in PP, isotactic PP, PPH or PVDF. Diaphragms in PTFE backed by Neoprene, EPDM, Viton or natural rubber — the PTFE face gives the chemical resistance and the rubber backing the elasticity. SS 304 or SS 316 parts and fasteners are available on request.
What size, end connections, operation and test pressures apply?
15 mm to 150 mm with flanged ends to ANSI B16.5 150#, BS 10 Table D/E/F or DIN standard. Hydrostatic test 10 kg/cm² on body and seat. Operation by manual handwheel, or pneumatic actuator in air-to-open, spring-to-close configuration — which fails closed on air loss, the usual requirement on a chemical dosing line.
Why choose a diaphragm valve rather than a PVDF ball valve?
Because the diaphragm seals the process off from the stem completely, so there is no packing, no rotating seal and no cavity. That makes it the better choice for slurries, crystallising media and anything that would score the seat of a PVDF ball valve, and it throttles far better. The trade-offs are higher pressure drop and a diaphragm that is a wearing part.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS is described as the largest diaphragm and ball valve exporter from India, manufacturing at its own works since 1978 and ISO 9001:2015 certified. The minimum order quantity is 20 pieces. PVDF bodies, PTFE-faced diaphragms with alternative backings, stainless fasteners and air-to-open pneumatic actuators are built to order.
