2-Piece 2000 WOG Carbon Steel Ball Valve Full Port BSPP End
Product Overview
The STV-Q11F-2000WOG 2-Piece Carbon Steel Ball Valve is designed for critical applications requiring reliable flow control under high pressure conditions. This full port valve features BSPP threaded end connections and is rated for 2000 WOG (Water, Oil, Gas) service, making it suitable for a wide range of industrial media including fresh water, sewage, sea water, air, steam, food, medicine, chemicals, various oils, and acid/alkali solutions.
The two-piece design offers significant advantages for maintenance and installation. The valve body can be disassembled into two main parts, allowing for thorough cleaning of the ball, seat, and other internal components. This design also facilitates easier installation in tight spaces and simplifies maintenance procedures, reducing downtime and operational costs.
