Product Description

Pneumatic Actuated Wafer Type V Port Segment Ball Valve is a rotary ball valve with a core seat made of metal or metal to PTFE sealing and matching. It combines the best control characteristics of the ball valve and butterfly valve into one, making it highly versatile for various industrial applications. It can be utilized efficiently as both a control regulating valve and a reliable shut-off valve.

Product Features

V Incision Design

The shear force between the ball and the metal seat type V incision is especially suitable for media containing fiber, small solid particles, and pulp.

Small Pressure Loss

Features fully open flow capacity and small pressure loss; prevents media from depositing in the body cavity.

Long Service Life

Utilizes a spring-loaded movable seat structure, preventing jamming between the ball core and valve seat while ensuring reliable sealing.

Accurate Regulation

Offers accurate regulation with an approximately equal percentage flow characteristic and a maximum adjustable ratio of 100:1.

Frequently Asked Questions

Q1: What are the primary advantages of the V-port design? A: The V-shaped incision creates a shear force between the ball and the seat, which is ideal for handling media containing fibers or small particles, preventing clogs and ensuring a clean cut during operation.

Q2: Can this valve be used for both regulation and shut-off? A: Yes, it is designed to combine the flow control characteristics of a butterfly valve with the sealing performance of a ball valve, making it suitable for both precise regulation and reliable shut-off.

Q3: What is the maximum adjustable range of the valve? A: This valve features a large adjustable range with a maximum adjustable ratio of up to 100:1, allowing for highly accurate flow positioning.

Q4: What temperature ranges can this valve withstand? A: It depends on the seal type: Hard seals can handle temperatures from -40 to 300ºC, while soft seals are rated for -40 to 180ºC.

Q5: Is the valve seat prone to jamming? A: No, the valve uses a spring-loaded movable seat structure specifically designed to prevent the ball core and seat from jamming, ensuring a long and reliable service life.

Q6: What driving methods are supported? A: The valve can be operated through various means including Manual control, Electric actuation, Worm wheels, and Pneumatic systems.
