FlowPro
High performance Valve
Application
Control of gases, vapours and liquids.
The modular concept of valve, multi spring actuator and our standard Positioner facililates trouble free expansion to allow for the communication capability of the FlowPro Valve System.
With its simple design the FlowPro modular concapt has a wide range of application.
Product features
Body shape gives optimum flow characeristic
• Excellent flow dynamics when correctly selected
• Heavy top guided plug
• Largest posible cv-values
Long service life and operational reliability
• With aggressive or evaporating media due to sturdy design
• Strong guides, give minimum vibration and wear
Replaceable trim
• Simple maintenance as the valve body remains in the pipng when trim is replaced
• Screwed seat
Wide range of application
• Up to 8 cv-values are available per size

Certificates and Licenses
• Quality assurance system certificated acc. EN ISO 9001 : 2000 incliding product development
• PED 97/23/EC Module H
• AK 7 design acc. To DIN V19250/51 fo Valves
FlowAct
High performance Actuator
Application
For installation on control valves, direct or reverse action, for controlled or on/off operation.
Product features
• Multi-spring compact design
• Radial spring, arrangement permits a low mounting height
• Low volume between diaphragm and case gives fast response times
• Strong operating force by permissible pressure supply of 6 bar / 87 psig
• Permissible ambient temperature -40 up to 80°C / -40 up to 176°F
• Stable guided stem
• Fabric-reinforced roll-type diaphragm with minimum area variation due to stem position on loss in operating force for various stroke positions - linearity is retained
• Stem bushing requires no maintenance
• Stable yoke in spheroidal cast-iron
• Central mounting on the control valve
• Yoke and stem coupling with mouning surfaces according to NAMUR(DIN IEC 65 B CO)
• Top resp. lateral mounted hand wheel
Operation
The diaphragm is actuated by the control signal. The actuator stem moves as soon as the diaphragm force exceeds the counterforces of the springs. There are two operational modes depending on the arrangement of the spring package:
1. Stem extends by air failure
2. Stem retracts by air failure
The control valve can be opened or closed with a rising signal. On air failure, the actuator is set back to the zero positioner by spring force (fail-safe position)Quality assurance system certificated acc. EN
