V-port Ball Valve

A v-port ball valve is a control valve with a v-shaped seal or v-shaped ball. The 'v' shape allows for better fluid control. The molded v-bore differentiates the v-port ball valves from other ball valve types. The v bore is available in either a 15⁰, 30⁰, 45⁰, 60⁰, or 90⁰ angle.

V-port ball control valves are generally preferred for fluid control since they produce linear flow characteristics. A v-port ball valve's flow characteristics are different from that of standard port ball valves. The fluid flow through a v-port ball valve increases linearly with an increase in shaft rotation. V-ball control valves have high strength to withstand the high velocity of fluids flowing through the valves.

V-Port ball valves are an efficient and versatile solution for flow control in a variety of industrial applications. Their robust design, tight shutoff mechanism and low pressure loss coefficient make them a reliable and effective choice. In addition, advances in materials, technology and design have further improved their performance, durability and automation capabilities.

The V-shaped ball valve is an advanced control valve with a right-angle rotary structure.lt can be used with a valve positioner to achieve proportional adjustment.It can be used with a two-position five-way solenoid and control box to achieve on-off control. Suitable for the control of gas, liquid and solid particle media. Since there is nogap between the valve core and the valve seat, it has great shear force and self-cleaning performance.It is especially suitable for the control of suspensions and solidparticles containing fibers or tiny solid particles. Therefore, this product can be widelyused in automatic control systems in industrial sectors such as petroleum, chemicalindustry, papermaking, chemical fiber, electric power, metallurgy, pharmaceuticals,and environmental protection.

V-port Ball Valve is a high-quality industrial valve designed to deliver exceptional performance and precision control in fluid flow applications. With its innovative V-shaped port, this valve offers superior flow control by providing a linear flow characteristic, allowing for accurate modulation and throttling.

Crafted with precision engineering and using the finest materials, V-port Ball Valve ensures reliable operation and durability even in demanding environments. It features a robust ball design that ensures tight shut-off and minimizes leakage. The valve's compact and versatile design makes it suitable for a wide range of industries, including oil and gas, chemical, power generation, and water treatment.

1.lt has an elastic load pressure auxiliary sealing seat to ensure close contact between the valve seat and the ball core.

2.It has an integral valve body structure and there is no possibility of potential leakage .

3. lt has equal percentage characteristics and a wide range of The control range and particularly stable control process can be widely used in avariety of processes.

4.The vave stem and the ball core are connected by involute splines. When the tooth profle is loaded, there is a radial force on the tooth thatcan automatically Centering effect, and each tooth is evenly stressed, making it high strength and long life.

In general terms, ball valves are used in a variety of applications and markets, such as transmission and storage, gas processing, industrial, and many more. V-Port Ball valves are commonly used in the acid transfer, agriculture, bleach chemicals, water treatment, leaching acid, pharmaceuticals, waste processing, and food processing.

V-port ball valve open (left) and closed (right) configurations.

1. The core structure differs between the two. The flow passage of an O-type ball valve is a complete circle with double-seat sealing. The V-type ball valve has a 1/4 semi-spherical valve core with a V-shaped opening on one side, using a single-seat seal. There are also designs with a full spherical valve core, with a V-shaped flow passage on one end, in either a single-seat or double-seat sealing form.

2. Different suitability for media. O-type ball valves are mostly used for clean media or media with few suspended particles. When equipped with PTFE (polytetrafluoroethylene) seat seals, they can achieve zero leakage. However, in media with a high impurity content or granular media, the central cavity may become blocked, causing the ball valve to seize and malfunction. V-type ball valves often use metal hard seals and are suitable for media containing fibers, fine particles, and slurry. The V-shaped opening can cut through fiber media, making them widely used in the papermaking industry. Due to the use of a partial spherical valve core and a single-seat seal, it effectively prevents media blockage in the valve.

3. Different suitability for process control requirements. O-type ball valves are mainly used for on-off control, with poor regulating performance. When equipped with an AT pneumatic piston actuator, they can achieve fast shut-off. V-type ball valves have a V-shaped opening, providing good adjustability with a high adjustable ratio, reaching 100:1 or higher. When equipped with pneumatic and electric actuators, they are mainly used for regulating control but can also be used for on-off control.

4. Different flow characteristics. The flow characteristic of O-type ball valves is quick opening, suitable for on-off control. The flow characteristic of V-type ball valves is approximately equal percentage, suitable for regulating control.

5. Different flow passage sizes. O-type ball valves generally have two flow passage sizes: full bore and reduced bore. V-type ball valves have different flow passage sizes based on process and design requirements, usually reduced bore. Different ball cores can be replaced to meet various flow rate requirements.
