Industrial Valves: A Critical Component in Modern Systems
In today’s increasingly advanced and interconnected industrial world, valves serve as one of the most indispensable components in ensuring the control, safety, and efficiency of fluid and gas systems. From upstream oil extraction to downstream refining and complex chemical processes, every industrial application depends on a robust valve infrastructure to function smoothly.
Valves perform a range of critical tasks: they regulate flow rates, isolate system sections for maintenance, prevent reverse flow (backflow), maintain optimal pressure levels, and protect equipment integrity. A single failure in a valve can lead to downtime, safety hazards, and financial losses — emphasizing the importance of selecting the right valve for every application.
Among the different valve types used across industries, ball valves, gate valves, check valves, and control valves are the most common due to their versatility, durability, and performance across varying pressure and temperature conditions. Of these, the ball valve is particularly renowned for offering tight shut-off and low torque operation, making it ideal for applications that demand high-integrity sealing.
In this product spotlight, we take a closer look at one of the most advanced valve solutions in the market: the Kitz Soft Seated 3-Piece Body Trunnion Mounted Ball Valve. Designed and manufactured by Kitz Corporation — a global leader in valve technology — this model offers best-in-class performance for demanding industrial environments.
Comprehensive Product Description: Kitz Trunnion Mounted Ball Valve
Overview
The Kitz Soft Seated 3-Piece Body Trunnion Mounted Ball Valve is engineered for high-pressure, high-integrity operations in oil & gas, petrochemical, and power generation industries. It features a trunnion-mounted design — where the ball is anchored at both ends — allowing for more stable performance, reduced operational torque, and enhanced sealing under varying pressure conditions.
Unlike conventional floating ball valves, the trunnion-mounted design keeps the ball in place, minimizing the stress on seat rings and ensuring longer service life. The soft-seated configuration delivers bubble-tight shut-off and is compatible with corrosive or aggressive media, thanks to advanced seat materials like RTPFE, RNylon, and DEVLON V.
Key Features
✅ Three-Piece Bolted Body Design
The three-piece body construction simplifies in-line maintenance and inspection. Operators can access internal components without removing the valve from the pipeline — significantly reducing downtime and increasing operational flexibility.
✅ Trunnion-Mounted Ball
This design reduces the torque required to operate the valve and minimizes the load on the seats. It ensures tight shut-off performance even under high pressure, making it ideal for ASME Class 150 through Class 1500 systems.
✅ Soft-Seated Sealing
The valve uses high-performance seat materials such as RTPFE, RNylon, and DEVLON V that ensure chemical resistance, durability, and reliable tight sealing.
✅ Fire-Safe Design
Tested and certified to fire safety standards, this valve maintains its integrity and functionality during fire or thermal incidents — a critical feature for hazardous industrial environments.
✅ Automatic Cavity Pressure Relief
This self-relieving mechanism releases excess pressure in the valve cavity, especially under blocked-end conditions, thus preventing potential system failure and improving operational safety.
✅ International Standard Compliance
Fully compliant with API 6D, ISO 14313, NACE MR0175, and other major global valve design and performance standards — ensuring compatibility with international systems and best practices.

Industrial Applications of Kitz Trunnion Mounted Ball Valves
Due to their robust construction and advanced sealing capabilities, Kitz Trunnion Mounted Ball Valves are widely used in several critical industries. Here’s how this valve adds value in different operational environments:
1. Oil & Gas Industry
These valves are deployed in upstream extraction, midstream transport, and downstream refining. They’re commonly used for flow isolation, emergency shutdown systems (ESD), and pig launcher/receiver operations. Their fire-safe design and pressure resistance make them ideal for these harsh environments.
2. Petrochemical & Chemical Plants
Valves in this industry must handle aggressive fluids and gases. Kitz trunnion valves, with soft-seated construction and chemically resistant materials, are perfect for ensuring zero-leakage performance in these conditions.
3. Power Generation
Whether in fossil fuel-based plants or nuclear energy facilities, this valve type handles high-temperature steam and pressurized water lines efficiently. Their reliability reduces the risk of system failure and maintenance interruptions.
4. Industrial Processing Plants
In sectors like pulp and paper, food and beverage, and pharmaceuticals, hygiene and control are crucial. The modular body design and precise flow control of Kitz valves enable customized solutions tailored to process-specific needs.
5. Water Treatment and Transmission Systems
Kitz trunnion valves are also used in high-flow municipal water supply systems where durability and tight shut-off are essential. Their low-pressure drop and high Cv value make them a cost-effective solution in waterworks.
