Side-Entry Flanged Control & Choke Valves

SFDAL Series

Like all Cyclonic valves, the SFDAL Series is built with the Cyclonic Design Difference. When you need to control a wide range of pressures and flow rates of gases or liquids, Cyclonic’s superior design gives you accurate control and a long safe valve life.

Technical Data >>


Actuation Friendly
Pre-drilled for simple in-line
actuation changes, whether
manual or automated.
Field Lubricated Stem
Can be used with handle or actuator.
EDS™ Erosion Detection System
(Patent Pending)
Provides erosion
Low Torque
Exclusive internal gear drive
requires less torque, often
allowing use of smaller, less
expensive actuation. Precise
repeatable control.
In-Line Flow Path
Minimizes pressure
drop, erosion and cavitation.
Side Entry Access Bonnet
Allows easy changeout of the discs to
accommodate changing flow conditions, and for
complete inspection and maintenance - all without
taking the valve out of line, or removing the actuator.
100% Testing
Each valve we make is tested
to ANSI B16.34 / API 598
Tungsten Carbide
Control discs and extended
downstream erosion protection.
