Two Piece Ball Valve

Two Piece Ball Valve Manufacturer

At MVS Valve, we specialize in manufacturing precision-engineered Two Piece Ball Valves designed for dependable shutoff and long-term performance in demanding industrial environments. Our Two Piece Floating Ball Valve, designed in compliance with API 608 standards, is ideal for industries such as oil and gas, chemical processing, water treatment, LPG, and propane systems. These valves are manufactured using high-quality Carbon Steel, Stainless Steel, and Duplex Stainless Steel, and are available with Full Port Flanged End Connections in CL 150 and CL 300 ratings, making sure compatibility with global pipeline requirements.

The compact yet strong two-piece body design is available in both full and reduced bore options, giving engineers flexibility in flow management. Each Carbon Steel Two Piece Ball Valve Full Port Flanged CL 150 – CL 300 is crafted to provide a high flow rate, resistance to wear, and operational efficiency in high-pressure systems. Our Stainless Steel Two Piece Ball Valve Full Port Flanged CL 150 – CL 300 models offer excellent corrosion resistance and reliability, especially in harsh fluid applications. For highly corrosive and offshore uses, the Duplex SS Two Piece Ball Valve Full Port Flanged CL 150 – CL 300 is the preferred solution due to its enhanced mechanical properties and long service life.

For automated systems, Pneumatic Two Piece Ball Valve Full Port Flanged CL 150 – CL 300 variants are available, offering rapid actuation and tight shutoff in mission-critical applications. We also offer models with ISO direct mount configurations, such as the SS ISO Mount Pad Fire Safe Two Piece Ball Valve Full Port Flanged CL 150 – CL 300, which come with fire-safe construction, anti-static devices, and blowout-proof stem designs to meet international safety standards. These features, along with a gland-type sealing arrangement and locking provisions on request, ensure reliable and secure valve operation under all working conditions.

Whether used manually or with actuators, our Two Piece Ball Valves provide low torque operation, excellent sealing, and a longer smooth operational life. The valves are engineered not just for fluid control, but for peace of mind—backed by MVS Valve’s commitment to quality, safety, and industry-leading support.

What is a two piece ball valve and how does it work?

The body is cast in two parts that bolt or screw together, trapping the ball and seats between them. A 90° turn of the lever opens or closes the full bore. Splitting the body means the ball and seats can be reached for inspection and replacement, though the valve normally has to come out of the line to do it. It is the most widely used ball valve construction because it balances cost against serviceability.

Which body, ball and seat materials are available?

Body and end piece in WCB, CF8 (SS 304), CF8M (SS 316), duplex and other alloys. Ball in SS 304, SS 316 or ENP coated; stem in SS 304, SS 316, EN8 or ENP coated. Seats in PTFE, RPTFE, carbon-filled PTFE, PEEK or metal; seals in PTFE, Viton or graphite; fasteners in high tensile steel or stainless. For corrosive duty the same valve is built fully lined as the PTFE Lined Ball Valve.

What size, pressure class and standards apply?

½″ to 12″ with flanged ends, Class 150# to 300#, full bore. Designed to BS EN ISO 17292 (BS 5351), BS EN ISO 12516, BS EN 1983, ASME B16.34 and API 6D, tested to API 598, and available with fire safe design to API 607 / ISO 10497 — which matters wherever a seat fire could otherwise leave the valve leaking.

Two piece or three piece — which do I need?

A two piece valve is lighter and less expensive and covers the same ½″–12″ range. A three piece ball valve lets the centre section be lifted out while the end caps stay bolted to the pipework, so seats can be changed without breaking the line — worth the extra cost wherever downtime is expensive or the media fouls seats quickly. For routine isolation on clean service, two piece is the normal choice.

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. Fire safe construction, special alloys, PEEK or metal seats and complete pneumatic or electric actuated assemblies are built to order.
