Highlight: Welded ball valve with strainer
Product introduction:
Welding ball valve is an integral welding ball valve made of carbon steel seamless steel pipe, with a valve stem made of AISI303 stainless steel and a ball body made of AISI304 stainless steel. It is finely processed and ground, and has excellent sealing performance and corrosion resistance The sealing adopts carbon reinforced PTFE inclined elastic sealing ring with negative pressure on the spherical surface, achieving zero leakage and long service life. There are various connection methods for welding ball valves, such as welding, threading, flanges, etc., for users to choose from. The driving methods can adopt transmission structures such as handle, turbine, pneumatic, electric, etc. The switch is flexible and lightweight.

Product features:
1. Fully Welded Body: Integrally welded to eliminate external leakage risks, with a compact structure for easy installation.
2. Low Torque Operation: Equipped with PTFE self-lubricating metal bushings to minimize friction, ensuring smooth
opening and closing.
3. Double Block and Bleed (DBB): Allows discharge of media from the valve body when the valve is closed and under
pressure, ensuring safety.
4. Dual Piston Sealing: Bilateral pressure sealing on the seats; if the upstream seat leaks, the downstream seat
automatically seals to prevent leakage.
5. Reliable Sealing: Floating seat + spring preload, combined with particle-resistant composite seals to achieve zero
leakage, adaptable to different working conditions.
6. Multiple Actuation Options: Available with manual (handle/worm gear), pneumatic, electric, etc., for convenient
operation. Factory provides full assembly, transportation, and commissioning.
