Top-mounted integral type

Description

Top-mounted integral type

The Top-Mounted Integral Type valve offers a streamlined solution for efficient flow control and on-site maintenance. Featuring a rugged one-piece body with top-entry bonnet, this valve allows safe, inline access to internals—ideal for changing seats, packing, or ball components without removing the valve from the pipeline. Its integral top-mounted structure ensures ease of service, reduces system downtime, and simplifies maintenance operations.

Built to industrial standards, this valve is available in forged or cast carbon steel, stainless steel, or alloy-steel bodies, supporting full-bore or reduced-bore designs with pressure ratings typically Class 150 to Class 600. The full-bore configuration offers minimal pressure drop, while the reduced-bore provides enhanced flow control and compact installation. Internally, the valve uses floating or fixed ball technology with PTFE, PEEK, or metal-seated options to ensure leak-free performance across demanding applications. The integral design supports manual, worm-gear, pneumatic, electric, or hydraulic actuation, and ISO 5211 pad compatibility ensures straightforward automation.

Safety and reliability are reinforced by anti-static devices, blow-out-proof stems, live-loaded gland packing, and optional fire-safe construction according to API606/607. Pressure and leakage testing is conducted per API 598 or EN 12266‑1 to guarantee performance and integrity.

With its top-mounted integral design, the valve is perfect for applications where maintenance efficiency, process integrity, and operational continuity are critical. It is commonly used in oil and gas, petrochemical plants, power generation, chemical processing, and water treatment facilities. Switchover of internal components can be performed under full-pressure conditions, significantly reducing service time and cost.

This valve is an excellent retrofit or new-install choice when inline maintenance is prioritized. It allows operators to replace worn components quickly, reducing system interruptions and enhancing productivity. Whether specified for floating or fixed balls, soft or metal seats, the Top-Mounted Integral Type valve delivers secure shut-off, operational flexibility, and streamlined maintenance for modern industrial pipelines.
