DESCRIPTION

Forged Trunnion Ball Valve Working Principle

The Forged Trunnion Ball Valve uses a fixed ball supported by upper and lower trunnions to control the flow of liquids and gases. Unlike floating ball valves, the ball remains stationary while the seats move toward the ball under line pressure. As a result, sealing performance remains reliable even under demanding operating conditions.

The mechanical anchoring system absorbs pressure loads and reduces friction between the ball and the seats. Furthermore, the lower operating torque allows the valve to use smaller actuators, reducing installation and operating costs.

Benefits and Advantages

The Forged Trunnion Ball Valve provides dependable sealing performance across both low-pressure and high-pressure applications. Therefore, it is widely used in industries that require safe and reliable isolation.

The spring-loaded seat design automatically compensates for pressure changes while maintaining consistent sealing performance. Moreover, reduced seat wear and lower operating torque help extend service life and minimize maintenance costs.

Fully forged pressure-retaining components provide exceptional mechanical strength and structural integrity. In addition, premium stem sealing materials reduce emissions and ensure reliable long-term operation.
