Critical Service Valve Applications for the Upstream Oil and Gas Industry
ValvTechnologies’ valves are built to withstand the most severe applications. High-temperature, high-pressure, high-cycling, abrasive, corrosive and caustic media have all been considered in the design of our product line. In the oil and gas industry, valve performance can be compromised by combinations of process conditions such as high temperature, high pressure, high solids or high cycles. The ValvTechnologies design is quite unlike that found in floating and trunnion-style ball valves and is a complete departure from the traditional gate and plug valves found in this industry.
The ValvTechnologies design uses an integral seat rather than loose seats. The integral seat provides a stable platform onto which the ball is constantly loaded with very high force, making it impossible to trap solids between the ball and seat. When the ball is in the open position, the seats are protected from the flow. The integral seat also eliminates the potential for leakage between a loose seat and the valve body.
The ball and integral seat are hard coated with chrome carbide or tungsten carbide using ValvTechnologies’ proprietary HVOF process called RiTech®, or Robotically Integrated Technology. This increases the surface hardness by nearly an order of magnitude beyond that of conventional weld-overlay hardening techniques. High surface hardness makes the sealing surfaces impervious to erosion and abrasion. The base metal is not altered by the hard coating and maintains compliance with the hardness requirements of NACE MR0175.
A high-strength Belleville® spring provides force to load the ball into the seat. This design solves many of the problems related to buildup and corrosion in trunnion bearings and eliminates free space between the ball and seat. Unlike the floating-type ball valves, the ValvTechnologies design does not require upstream pressure to provide tight sealing. The spring also makes the valve inherently self-relieving and provides anti-static protection.
The non-pinned, blowout-proof stem provides a measure of safety and reliability that is essential in critical service valves. The stem is inserted internally when the valve is assembled. Live-loaded Grafoil and stainless steel packing guarantees’ zero emissions. The valves are available in a wide variety of sizes and materials and in ANSI pressure classes 150-4500 and API 5,000 – 20,0000.
Bi-directional and double block and bleed configurations are available. ValvTechnologies valves used in oil and gas applications are guaranteed to be zero-leakage and zero emissions.
The ValvTechnologies’ severe service valve design is a departure from traditional products found in the upstream and midstream sectors of the oil and gas industry.
In the oil and gas industry, valve performance is challenged by combinations of process conditions such as high-temperature, high-pressure, high-solids, high-cycle and erosive environments. The ValvTechnologies’ design is quite unlike that found in typical floating and trunnion-style ball valves and is a complete departure from other valves found throughout the industry.
Our product portfolio employs two valve design platforms: seat supported and trunnion-supported technologies.
The technology platforms have the following features in common:
- Address severe-service fluid isolation and containment challenges
- Available for use in a wide range of temperatures
- Meet or exceed fugitive emission standards as defined in ISO 15848, TA LUFT
- Provide superior sealing performance
- Full compliance with all oil and gas related QA surveillance requirements
- Time-proven metal to metal sealing systems
- Proprietary coating technologies available for a variety of severe service conditions
The seat supported design incorporates an integral downstream seat. The integral seat provides a stable platform onto which the ball is constantly loaded with very high force, making it impossible to trap solids between the ball and seat. When the ball is in the open position, the seats are fully protected from the process flow. The integral seat design eliminates the potential for leakage between a loose seat and the valve body, a common problem in a typical floating ball valve design.
The V Series is designed to ANSI B16.34, fire-safe per API-607, tight-shut-off per ISO-5208 Rate A.
ValvTechnologies’ TrunTech® is our trunnion supported ball valve; designed to address the severe service demands of the upstream and midstream oil and gas industries. The proven seat seal design provides long life and tight shut-off in very abrasive and erosive environments that lead to greater up-time and less downtime for our clients.
The TrunTech® is designed to API-6D and API-6A, fire-safe per API-607 (API-6D) and API-6FA (API-6A), tight-shut-off per ISO-5208 Rate A (API-6D) and PSL-3/3G (API-6A).
