PQ340H, Katup Bola Eksentrik Segel Keras PQ340Y
The PQ340H/Y hard-seal eccentric ball valve utilizes an eccentric valve body, eccentric ball, and valve seat. As the valve stem rotates, it automatically centers itself along a common trajectory, tightening further during closing to achieve a perfect seal. The ball and seat are completely separated, menghilangkan keausan pada cincin penyegel dan mengatasi masalah keausan konstan antara permukaan penyegelan dan bola pada katup bola tradisional. Bahan elastis non-logam tertanam di dudukan logam, providing excellent protection for the seat’s metal surface. This product is particularly suitable for media in the steel industry, aluminum industry, fiber, small solid particles, pulp, coal ash, and petroleum gas.

Structural Features
1. The valve seat features an external step that mates with the internal step of the valve body, preventing the ball from jamming or disengaging from the seat.
2. Utilizing an eccentric valve body, eccentric ball, and valve seat, the valve stem automatically centers itself along a common trajectory during rotation. During closing, the valve tightens further, achieving a perfect seal. Karena itu, the eccentric hemispherical valve offers reliable and safe sealing performance. Saat katup membuka dan menutup, the ball completely disengages from the seat, eliminating wear on the sealing surface and overcoming the problem of constant wear between the valve seat and ball sealing surfaces in traditional ball valves.
3. Non-metallic elastic material is incorporated into the metal seat, providing excellent protection for the metal sealing surface.
4. The hemispherical design creates a shearing effect between the ball and seat, making it particularly suitable for media containing fibers, small solid particles, and slurries.
5. Saat terbuka penuh, it offers high flow capacity, low pressure loss, and prevents media from accumulating in the valve body cavity.
6. This product has precise adjustment and reliable positioning functions, the flow characteristics are approximately percentage, the adjustable range is large, and the maximum adjustment ratio is 100:1.
