Mascot VFlo: V-Notch Segmented Ball Control Valve

Mascot VFlo

A Segmented Ball Valve from Mascot Valve

The VFlo – Segmented Ball Valve is designed to provide effective control for demanding applications. It is a rugged design segmented ball valve which overcomes the problems of harsh, particle entrained processes, and fibrous/unclean services. The VFlo also provides accurate, reliable control in a broad rang

Metal Seal: Using the pressure drop across the valve, flex-lock sealing energises the seal to bubble tight shutoff in either flow direction. ANSI class IV is achieved with a metal seal.

Soft & Dual Seal: Using the pressure drop across the valve for soft sealing as well, the VFlo energises the seal to bubble tight shutoff in either flow direction. ANSI class VI is achieved with a soft seal and ANSI class IV with a dual seal.

The Soft seal ring is standard for the VFlo and utilizes a 316 SS or Inconel Ring as a backup in conjunction with a Filled PTFE / PEEK seat. Such design provides for a quick and easy replacement in case of failure. The backup ring also provides shear action hence scraping any developments on the ball.

CavFlo Cavitation Control Valve Trim by MASCOT


Whenever the pressure of flowing liquid through a restricted area of a control valve drops below the vapor pressure of the liquid, and recovers to a pressure above the vapor pressure, cavitation damage to the control valve and connecting piping may occur. 

In the first stage of cavitation, vapor bubbles form downstream of the restricted area at the vena contracta (point of narrowest fluid constraint). The enlarging passage at downstream of the vena contracta reduces the velocity and thereby associated pressure recovery causes the vapor bubbles collapse or implode suddenly.

This implosion of the bubbles on metal surfaces causes stresses, eventually resulting in tearing away particles of the metal from the surface towards inward. Cavitation damages the plug and seat of a control valve as throttling occurs at the restriction, in the clearance between the plug and seat ring. If the vapor bubbles implode near them, the valve body and piping can also be damaged.

MASCOT's CavFlo Trim utilizes many small holes for diametrical flow through the walls of the seat retainer. As the valve plug lifts, increasing pairs of holes are opened. Each hole discharges a jet of cavitating liquid at the center of the retainer, which impinges with a jet of liquid admitted through the opposing hole. The impinging fluid jets form an area of pressure recovery and a fluid cushion. This phenomenon collapses the vapor bubbles in the fluid stream, away from metal parts preventing damages.
