The product

Features

Series 1610 (Multistage Multistep Trim) Ideal for selection with fluids having contaminated particles.
Design confirming to ASME 16.34, IEC 60534-2-5.
Excellent flow control rangeability.
Modified linear flow characteristic.
Leakage class up to class V for metal seating & class VI for soft seating special design.
Leakage class as per FCI 70.2.
NACE MR 0103 and MR0175 compliance.
Erosion, vibration resistant and anti-noise trim design.
Available in globe and angle types.
Flowed over the plug
Excellent solution to erosion, vibration & high noise levels in handling high pressure fluids because of large flow passage and fluid cutting action provided by multiple steps, these valves are well suited for application involving fluid particles where drilled hole multistage and disc stack valves would fail.
Nominal sizes up to 100mm, pressure class #600 to #2500
Temperature -196^oC to 650^oC
Available up to 6 stages.

Flow Characteristics

Our engineering team employs modern engineering tools, including 3D Modelling, Finite Element Analysis and CFD analysis to guarantee that our products are designed with the utmost integrity and reliability. Thanks to ongoing Research & Development and the integration of the latest engineering tools, Dembla’s Severe Service Valves represent the forefront of control valve technology.

Applications

Dembla series 1610 Multi step design are capable of handling high pressure drops without instability problems.
These are suitable where multistage multi hole control valve fails either because of micro flow rates and where the contaminated fluid would cause blockage of drilled holes.
Multistep trims design has modified linear inherent characteristic and has excellent range ability
