Casted End Entry , Side Entry Soft-Seated Floating Ball Valve 1&2PC Inch1/2"-12" Class150-300
Zaval casted end entry and side entry soft-seated floating ball valves are designed according to API 6D/ASME B16.34/BS5351/API 608. These valves are usually applied in low pressure at calss 150~300 with a wide temperature range (-46℃~343℃). The valves are fire safe designed and have been certified per API607 and API6FA. We can offer range consists of one-piece end entry (inch 3/4"-6") and two-piece split body (inch 1/2"-12") designs.Anti-Static Device, and blow-out proof stem, ISO5211 top mounting connection and lockable designs.
Design Features
1-piece,End Entry, Soft-Seated Casted Steel Inch 3/4"-10"( 20-150mm)

- Reliable Flow Locking Device: Valve is equipped with an integral locking device to secure flow.
- Blow-out proof stem: The lower end of the stem is T-shaped structured, protected by boss of body, which assures stem retention against any pressure.
- Fire Safe Design: Metal to metal sealing shuts off valve flow when soft sealing materials are destroyed by fire.
- ISO5211 connection dimension: actuator installation is simplified by using connection dimension recognized in international standards.
- Double "D" Stem Head: ensures handle lever will always be mounted correctly, parallel to the media flow, indicating valve open and closed positions.
- Emission-free Gasket: Low-emission graphite is employed in gasket to eliminate leakage.
