Eccentric Half Ball Valve-SHENGAO VALVE GROUP CO.,LTD

Eccentric Half Ball Valve

Innovative Design, Secure Sealing: Eccentric Half Ball Valves in Pipeline Systems

Eccentric half ball valves feature an offset design that ensures a tight seal even in high-pressure applications. The eccentric rotation of the ball reduces friction and wear, prolonging the valve's service life and enhancing its reliability. With their innovative design and superior sealing performance, eccentric half ball valves are well-suited for critical applications where tight shut-off is essential.

Key Components of Eccentric Half Ball Valve

Valve Body

Crafted from robust materials like stainless steel or cast iron, providing structural integrity and corrosion resistance.
Eccentric Half Ball

Features a unique design where the ball is offset from the centerline of the valve body, allowing for smooth flow modulation.
Stem

Constructed from corrosion-resistant materials, enabling reliable actuation and precise control of the valve.
Seat

Designed with wear-resistant materials such as PTFE or metal, ensuring a tight seal and preventing leakage.
Actuator

Facilitates the movement of the valve, allowing for remote or automated operation and precise flow control.
Seals

Utilize resilient materials like elastomers or PTFE, providing additional sealing to prevent fluid leakage.
Low Friction

The eccentric half-ball design reduces friction between the ball and seat, resulting in smooth operation and extended valve life.

Advantages of Eccentric Half Ball Valve

01

Optimized Flow Characteristics

The eccentric half ball design ensures smooth and unobstructed flow through the valve, minimizing pressure drop and turbulence, thereby improving efficiency and reducing energy consumption.
02

Bubble-Tight Shut-Off

The eccentric closure mechanism provides a tight seal against the valve seat, preventing leakage even under high-pressure conditions, ensuring reliable operation and process integrity.
03

Bi-Directional Sealing

Eccentric half ball valves offer effective sealing in both directions of flow, providing flexibility in installation and operation while maintaining flow control accuracy and reliability.
04

High Temperature Resistance

Constructed from heat-resistant materials and equipped with advanced sealing technologies, eccentric half ball valves can withstand high temperatures without compromising performance or integrity, making them suitable for demanding applications in extreme environments.
05

Minimal Maintenance Requirements

The robust design and high-quality materials used in eccentric half ball valves result in reduced wear and tear, prolonging service life and minimizing maintenance downtime and costs.

About Shengao Eccentric Half Ball Valve

Valve Body Type :	Ball
Valve Body Material :	Cast WCB carbon steel (general application), forged A105 carbon steel (general application), 304/316 stainless steel, alloy (corrosion resistance, extreme conditions), etc.
Valve Stem Material :	When the valve body material is ordinary carbon steel, the valve stem material is usually CR13 series martensitic stainless steel (American standard 410 and 420 stainless steel materials) or higher-grade austenitic stainless steel materials. When the valve body material is stainless steel, the valve stem material is usually austenitic stainless steel (American standard SS304, SS316) with a grade no lower than the valve body material and a higher grade corrosion-resistant alloy material (Hastelloy, Monel, Inconel alloy) etc.
Valve ball material :	The valve stem material is basically the same as the valve ball, plus carbon steel electroplating ENP anti-corrosion material, unless there are special requirements. The material of the ball is also ZrO2, AI2O3, SiC, Si3N4, etc.
Seat Material :	The hard-sealed metal valve seat and fixed soft-sealed valve seat support ring of the ball valve should be made of the same material as the ball.
Seat Sealing Surface Material :	The valve seat material is basically the same material as the ball, except for special requirements.
Pressure level :	Class 150-2500（ASME standards）or PN10~PN420
Actuator :	Manual handwheel, electric actuator, pneumatic actuator, hydraulic actuator
Temperature :	Depending on the material used, operation can occur within a temperature range of -50°C to +400°C, although specific materials may alter this range.
Size:	1/2'' to 60'' (DN 15-1500)
