Product Description

Product Description

The Class 300 Forged Steel Trunnion-Mounted Ball Valve from SLVCN delivers stable sealing and reliable performance for industrial pipeline applications. The trunnion-mounted ball ensures consistent operating torque, while the spring-loaded seat design provides automatic sealing compensation under changing pressure conditions. With Double Block and Bleed (DBB) capability and optional Single or Double Piston Effect seats, the valve offers enhanced sealing reliability and cavity pressure control. Safety is ensured with Anti-Blowout Stem, Anti-Static Device, and Fire-Safe construction compliant with API 607 / ISO 10497. Supporting manual, worm gear, electric, or pneumatic actuation with ISO 5211 direct mounting, the valve is easy to automate and maintain. Manufactured and tested to API 6D, ASME B16.34, and API 598, it meets Class 300 (PN50) pressure rating requirements for industries such as Oil & Gas, Chemical, Power, and Water Treatment.
