V-ball valve 2-(1)

Description

V-ball valve 2-(1)

The V‑Ball Valve 2‑(1) delivers control valve performance in a compact ball valve design, featuring a precisely machined V-notch in the ball to provide smooth, equal‑percentage flow regulation with bubble‑tight shut‑off. As a V‑port ball valve for flow control, it blends the simplicity and durability of a rotary ball valve with the proportional control characteristics of a globe valve. This low‑pressure drop V‑ball valve allows for high throughput and minimal pressure loss, even at partial open positions.

Manufactured in carbon steel or stainless steel, with V-notch angles of 30°, 60°, or 90°, this valve supports ANSI flange, threaded, socket-weld, or butt-weld end connections. It operates to Class 150–300 pressure ratings and handles temperatures up to 538 °C (1000 °F) with metal-seated versions or reinforced PTFE seats. As a high‑precision V ball valve, it offers Cv values down to 0.07 — ideal for fine control in small sizes or slurry-laden lines 

The floating ball design provides bi-directional bubble-tight shut‑off, with downstream pressure pressing the ball against the seat to enhance seal integrity under load. The V-notch edge slides against the seat, offering a self-cleaning effect that prevents clogging from particulates or fibrous media. This results in smooth, repeatable control over 95% of valve travel, making it well-suited to abrasive or viscous fluid systems in industries such as pulp & paper, water treatment, chemical processing, and slurry transport .

Ideal as an industrial V‑notch ball valve, it supports manual lever operation or integration with worm-gear, pneumatic, or electric actuators via an ISO 5211 mounting pad. Many designs feature one-piece or split-body construction for easy maintenance without special tools .

Its high rangeability, low actuation torque, and compact design reduce actuator sizing and operational cost. Unlike traditional valves, the V-ball valve achieves high shut-off pressure while providing controllable modulation, eliminating the need for separate throttling valves .

Use cases include steam tracer lines, chemical dosing, slurry metering systems, liquid level control, and applications where precise flow adjustment and reliable shut-off are both essential. By combining high-performance flow control with industrial-grade sealing, the V‑Ball Valve 2‑(1) delivers enhanced process stability, reduced maintenance, and extended service life in harsh operational environments.
