Single Piece Ball Valve
Single Piece Ball Valve Manufacturer
MVS Valve, our Single Piece Ball Valve is designed for precision, durability, and seamless performance in demanding industrial applications. Built as a two-way full port valve, it ensures unobstructed flow and minimal pressure loss—making it ideal for critical operations across sectors such as oil & gas, chemical processing, water treatment, and power generation.
This valve is available in multiple material configurations including Carbon Steel, Stainless Steel, and Duplex Stainless Steel—each crafted to meet rigorous safety and quality standards. Whether you’re using a Carbon Steel One Piece Ball Valve Full Port Flanged CL 150 – CL 300 or a Stainless Steel One Piece Ball Valve Full Port Flanged CL 150 – CL 300, you can expect superior resistance to corrosion, high structural strength, and reliable sealing even under harsh conditions.
For improved safety, our Single Piece Ball Valve is manufactured with Fire Safe Design, offering protection during high-temperature exposure. The ISO 5211 actuator mounting base allows for seamless integration with automation systems using either Pneumatic or Electrical Actuators. These features are complemented by manual operation options such as lever or gear unit for flexible field control.
Engineered to adapt, MVS also offers solutions like the Duplex SS One Piece Ball Valve Full Port Flanged CL 150 – CL 300, perfect for applications involving aggressive fluids or corrosive environments. Similarly, our Pneumatic One Piece Ball Valve Full Port Flanged CL 150 – CL 300 is widely used for automated processes where performance and responsiveness are critical. At MVS Valve, we don’t just manufacture valves—we deliver trust and efficiency with every unit. We provide the right solution to improve flow control and system safety.

What is a single piece ball valve and how does it work?
It is a quarter-turn valve whose body is made as one unbroken casting, with the ball and seats assembled through the end. A 90° turn of the lever rotates the bore into line with the pipe or across it. The full bore design means no flow restriction and no pressure drop when open. Because the body is not split, there is no body joint that can leak — but the valve also cannot be opened for service, so it is replaced rather than repaired when the seats wear.
Which body, ball and seat materials are available?
Body in WCB carbon steel, CF8 (SS 304), CF8M (SS 316), duplex and other alloys on request. 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, with seals in PTFE, Viton or graphite and fasteners in high tensile steel or stainless. Choose PEEK or metal seats where temperature or abrasion rules out PTFE.
What size, pressure class and standards apply?
½″ to 3″ with flanged ends, rated Class 150# to 300#, full bore throughout. Designed to BS EN ISO 17292 (formerly BS 5351), BS EN ISO 12516, BS EN 1983, ASME B16.34 and API 6D, and tested to API 598. MVS is ISO 9001:2015 certified and supplies test certificates with each order.
Single piece or two piece — which should I choose?
Choose single piece where cost and a leak-free body are what matter and the valve will not need servicing — general isolation on clean media in small bores. Choose a two piece ball valve where you want the option to open the valve and replace the ball and seats, or where you need sizes above 3″ or a fire safe design. Single piece is the cheapest ball valve per line; it is not the most serviceable.
Are you a manufacturer, and what are your minimum order quantity and customization options?
MVS has manufactured valves at its own works since 1978 — a manufacturer, not a trading house — is ISO 9001:2015 certified and exports across several continents. The minimum order quantity is 20 pieces. Special body alloys, seat materials and flange drilling are built to order. Send us the media, size, pressure and temperature and we will confirm the specification and delivery schedule.
