PVDF Butterfly Valve
PVDF Butterfly Valve Manufacturer
The MVS PVDF Butterfly Valve is engineered for demanding industrial applications that require safe and reliable flow control in highly corrosive and chemical environments. Designed in a compact wafer/sandwich style, this corrosion resistant PVDF butterfly valve fits seamlessly between ANSI B16.5 (150#) flanges, providing efficient sealing and optimal space utilization. With size options ranging from 50 mm to 300 mm, it offers flexible integration into diverse process systems.
Manufactured using high-grade PVDF, PP, and PPH materials, the valve delivers exceptional resistance to harsh media such as hydrochloric acid (HCL), nitric acid, sodium hypochlorite, and chlorinated paraffin wax. This makes it a preferred choice across the chemical industry, wastewater treatment facilities, and processing units handling chlorine, acids, and other aggressive fluids.
As a trusted PVDF butterfly valve manufacturer and PP butterfly valve supplier, MVS ensures that each valve is precision-engineered for consistent performance, long service life, and low maintenance. The acid resistant thermoplastic butterfly valve body design minimizes pressure drops while the thermoplastic disc and liner provide secure shut-off and enhanced media compatibility.
For plants looking to safeguard their systems from chemical wear and fluid contamination, MVS offers advanced solutions like the PPH butterfly valve for chemical industry and the chlorine resistant PVDF butterfly valve. The valve is ideal for installations where durability and chemical resistance are non-negotiable, particularly in acid processing lines, industrial effluent systems, and chemical dosing systems. Whether you need a hydrochloric acid resistant butterfly valve or a sodium hypochlorite butterfly valve supplier, MVS stands as a reliable partner in providing robust, high-performance thermoplastic butterfly valves tailored for harsh and specialized applications.

Frequently Asked Questions

What is a PVDF butterfly valve and how does it work?
A wafer or sandwich type butterfly valve with a one-piece moulded thermoplastic body in lug style. A quarter turn swings the disc into the liner to seal. The liner does double duty — it seals the disc and acts as the flange gasket on both faces, so there is no separate gasket to specify, fit or fail, and sealing works in both flow directions.
Which body, disc, shaft and liner materials are available?
Body in PP, isotactic PP, PPH or PVDF. Disc in PP, PVDF, HDPE or stainless steel as an option. Shaft in SS 304, 316, 304L or 316L. Seat and liner in EPDM, Neoprene, Viton or Nitrile — the liner material sets the chemical and temperature limit, so specify the media before the body.
What size, end connections, operation and test pressures apply?
50 mm to 300 mm, lug type to suit ANSI B16.5 150# flanges. Hydrostatic test 10 kg/cm² on body and seat. Operation is lever from 50–150 mm, and gear operated or pneumatic actuated at 200 mm and above — beyond 150 mm the torque needed is more than is comfortable on a hand lever.
Why does lug style matter on a thermoplastic valve?
Because each flange bolts to the valve independently rather than through it, so downstream pipework can be removed while the valve still holds pressure — and, importantly on a plastic body, the bolt load is taken in shear at the lugs rather than compressing the body between two flanges. That avoids the creep and distortion a wafer thermoplastic body can suffer when over-bolted.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS manufactures at its own works — since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. Stainless discs, PVDF bodies, alternative liner elastomers and gear or actuated assemblies are built to order.
