NEWCO Ball Valves: Technical Characteristics and Selection

Overview of NEWCO Ball Valves: Innovative Solutions from EV Group China

EV Group China offers advanced NEWCO pipeline valves, designed to provide reliable and long-lasting performance in the most demanding conditions, including the oil and gas sector and industrial water treatment systems. Based on the design features of the shut-off unit, NEWCO ball valves are divided into two key types:

  • Floating Ball Valves.
  • Trunnion Ball Valves.

NEWCO Floating Ball Valves

In the design of floating ball valves, the shut-off element is not rigidly fixed on supports. Its position is maintained by the stem, and tightness is achieved by the ball shifting under the pressure of the working medium towards the outlet seat. This ensures tight contact and a high degree of sealing for flow shut-off.

Technical characteristics of the Floating Ball series include nominal diameters from 1/2" to 12". These valves are designed for operation in pipelines with pressure classes Class 150, 300, and 600. Flanged versions (RF) are available with bodies made of high-quality steel grades WCB, LCC, and CF8M.

Key design features of the Floating Ball series:

  • Anti-blowout stem: The stem design prevents it from being ejected under pressure, providing additional safety, with the possibility of adjusting the packing.
  • GreenSeal environmental sealing system: An innovative sealing system that minimizes emissions into the environment and complies with strict environmental standards.
  • Integrated anti-static device: Prevents the build-up of static electricity and the risk of sparking, which is critically important for working with flammable media.
  • High-strength materials: Corrosion-resistant stainless steels are used for internal components, ensuring durability and reliability.
  • Fire Safe design: Compliance with international fire safety standards, ensuring the maintenance of tightness under high temperatures in case of fire.

The products comply with international standards: ASME B16.34/API 608 (design), ASME B16.5 (flanges), API 598 and 607 (fire resistance tests). This type of valve is optimal for compact systems where seat servicing is possible without complete removal of the valve from the main line.

NEWCO Trunnion Ball Valves & QuadroSphere

For pipeline systems operating under high loads and pressure, EV Group China specialists recommend the QuadroSphere series (trunnion ball valves). This design provides rigid fixation of the ball at two points (upper and lower supports), which significantly reduces the torque required to operate the valve. This ensures ease and accuracy of flow regulation even under significant pressure differentials.

Technical characteristics include diameters from 2" to 36" and pressure classes from Class 150 to Class 2500. Various connection options are available: butt weld (BW) and flanged connection (RF). Applicable materials for bodies and internal components include A105, LF2, F316, F51, ensuring high corrosion resistance and mechanical strength.

The advantage of the trunnion-mounted model is increased wear resistance and ease of operation at significant medium pressures. This is a reliable solution for long-distance main pipelines where minimizing operational wear and ensuring long-term trouble-free operation are priorities.

Where applied

NEWCO ball valves, offered by EV Group China, are widely used in various industries due to their reliability and versatility. In the oil and gas sector, they are used for transporting oil, gas, petroleum products, as well as in production, processing, and storage systems. In the chemical industry, these valves are used for working with aggressive media, acids, and alkalis, where high corrosion resistance is required. The energy sector uses them in thermal and nuclear power plants to control the flows of steam, water, and other process fluids. In addition, they are indispensable in water supply and sanitation systems, ensuring reliable shut-off and flow regulation of water in industrial and municipal networks. Their robust construction and high sealing make them an ideal choice for critical processes where safety and efficiency are priorities.

What to replace with / analogs

When it is necessary to replace NEWCO ball valves or select analogs, it is important to consider key parameters to ensure compatibility and adequate performance. Alternatives may include valves from manufacturers such as Cameron, Velan, Flowserve, or Kitz. When selecting an analog, the following aspects should be considered: pressure class (for example, Class 150, 300, 600, 2500), nominal diameter (from 1/2" to 36"), connection type (flanged RF, butt weld BW), as well as the material of the body and internal components (WCB, LCC, CF8M, A105, LF2, F316, F51). It is also important to consider the design of the shut-off element (floating ball or trunnion ball), as this affects operating characteristics and torque. When working with aggressive media, it is necessary to ensure that the analogous valve has appropriate corrosion resistance and a Fire Safe design, if required by the project.

What to clarify with the supplier

Before purchasing NEWCO ball valves or their analogs from EV Group China, it is extremely important to request and clarify a number of key points to ensure product compliance with your technical requirements. First, request full technical passports and certificates of conformity to international standards (ASME B16.34/API 608, ASME B16.5, API 598/607). Clarify information on the country of origin and the manufacturing plant to confirm the authenticity of the product. Request data on the materials of the body, ball, and seals, including chemical composition and mechanical properties, to ensure their suitability for your working medium. It is also necessary to obtain information on warranty obligations, service conditions, and the availability of spare parts. For large batches, inquire about the possibility of conducting an inspection at the manufacturing plant or providing full acceptance test reports. Finally, clarify delivery times, payment terms, and logistical details to avoid delays in the implementation of your project.
