DN65 65mm Ball Valve Gas Pipeline Use ISO5211 Mount Automated Upgrade Available

Description

The 65mm ball valve (DN65 / 2.5 inches) is a medium‑sized general‑purpose valve widely used in commercial building gas branches, HVAC circulation lines, food plant process water systems, and factory water supply/drainage branches. Featuring a full‑port design, it ensures smooth media passage. An ISO5211 standard flange base is provided on top, allowing later retrofitting with electric or pneumatic actuators for automated control. With reliable sealing performance, it safely isolates gas and water media, making it a common control valve in commercial fluid piping networks.

Core Specifications

Structural & Material Features
The valve body is integrally forged from 304 stainless steel, offering corrosion resistance and rust prevention – ideal for prolonged gas service. The full‑bore internal passage eliminates throttling dead zones, ensuring no pressure drop in gas delivery and minimising debris accumulation. The flame‑retardant PTFE sealing assembly provides excellent gas‑tightness, eliminating leakage risks when closed.

The stem incorporates a blowout‑proof and anti‑burst design, enhancing safety in gas applications. The standard ISO5211 top mounting pad enables straightforward actuator attachment without body modification, facilitating intelligent upgrades to building gas systems. The two‑piece split construction simplifies maintenance, allowing seal replacement without removing the entire pipe section.

Project Application
In a commercial building gas branch project in Santiago, Chile, the entire gas distribution network serving office towers and shopping malls was equipped with 65mm ball valves. The full‑port design ensures stable gas pressure, avoiding insufficient supply; the robust sealing eliminates leakage, reinforcing building safety. Some key buildings were pre‑fitted with electric actuators integrated into the fire‑protection and security system, enabling automatic gas shutoff in emergencies – significantly enhancing commercial building fire safety.

Key Advantages

1. Full‑port flow – minimal pressure loss in gas transmission, ensuring stable and adequate supply.

2. Explosion‑proof sealing construction – high tightness, offering a strong safety margin for commercial gas services.

3. Actuator‑ready base – supports intelligent upgrades for smart building retrofits.

4. Stainless steel body – rust‑resistant and durable, suitable for long‑term embedded wall or ceiling installation in building pipelines.
