High-Performance Trunnion Mounted Ball Valves for Oil & Gas Pipelines

Product Description

The Trunnion Mounted Ball Valve is engineered as a superior solution for critical isolation applications in the most demanding industrial environments, particularly within the oil, gas, and petrochemical sectors. Unlike floating ball designs, the Trunnion Mounted Ball Valve features a ball anchored by trunnions, significantly reducing operating torque and ensuring reliable, long-term sealing under high-pressure conditions. This robust construction makes it the valve of choice for mainline pipelines, refinery process lines, and offshore platforms, especially in the challenging climates of the Middle East.

Key Features & Design Advantages

Our Trunnion Mounted Ball Valve is built to exceed industry standards, incorporating essential safety and performance features:

  • Robust Construction: Available in full/reduced bore and two or three-piece body designs for flexibility.
  • Enhanced Safety: Features Double Block & Bleed (DBB/DIB) capability, API 607 fire-safe design, and an anti-static system for safe operation in hazardous areas.
  • Reliable Sealing: The blowout-proof stem and self-relieving seat cavity prevent pressure build-up and ensure fugitive emission control (optional testing available).
  • Operational Versatility: Designed for manual, electric, pneumatic, or hydraulic actuation to suit any plant requirement.

Frequently Asked Questions (FAQ)

Q1: What is the main advantage of a Trunnion Mounted Ball Valve over a floating ball valve?

A: The key advantage is its suitability for higher pressure and larger diameter applications. The trunnion-mounted design minimizes friction and torque, allowing for easier operation and reduced wear on seals, leading to a longer service life.

Q2: Are your valves certified for fire-safe applications?

A: Yes. Our Trunnion Mounted Ball Valves comply with API 607/API 6FA fire-safe testing standards, ensuring critical sealing integrity in the event of a fire—a vital requirement for Middle Eastern oil and gas facilities.

Q3: What does Double Isolation and Bleed (DIB) mean?

A: DIB, often found in a Trunnion Mounted Ball Valve, means the valve provides two independent sealing surfaces on each side of the ball. This allows it to isolate downstream pressure from upstream pressure and bleed the cavity between, enabling safe maintenance.

Q4: Why is an anti-static device important?

A: In hydrocarbon service, static electricity buildup can be a fire hazard. The anti-static device ensures electrical continuity between the ball, stem, and valve body, safely discharging any static charge.

Q5: Are your valves suitable for sour gas service?

A: Absolutely. We offer valves with materials compliant with NACE MR0175/MR0103 standards for handling sour (H2S-containing) hydrocarbons, common in many regional oil fields.

Engineered for durability and safety, our Trunnion Mounted Ball Valve delivers unmatched performance for pipeline and plant isolation, meeting the stringent demands of the global energy industry.
