Product catalog summary

Specification Overview

Design: The center body is designed for mounting between two flanges as per EN 1092-1 type 11 form B - PN10, with ANSI 150 available on request.
Media Compatibility: Suitable for various media including liquid, pulverized media with fibers, viscous media, drain water, sludge, and food, but not for steam.
Body Material: Options include grey cast iron (GG-25) with epoxy coating or stainless steel 1.4404.
Sealing Options: Standard options are NBR and EPDM, with FKM or PTFE available on request.
Gland: Comprises a 3-piece sealing set with GFO®-Faser - TWARON® edge reinforced, an O-ring, and synthetic fiber PTFE-lubricated.
Knife and Stem Material: Stainless steel options include 1.4301 or 1.4401 for the knife and 1.4305 or 1.4404 for the stem.
Functionality: Pneumatic double acting with bidirectional pressure discharge.
Pilot Pressure: Standard at 6 bar, with lower pressure available on request.
Temperature Range: NBR: -25°C to +90°C, EPDM: -35°C to +120°C, not applicable for all media.

Technical Features

Actuator: Pneumatic actuator with steel side parts, epoxy coated, ready for mounting limit switches.
Protection: Side protection available according to EU-Machinery directive 2006/42EC, at extra charge.
Sealing: Features a full cylindrical bore with flat seat sealing, cavity-free, and an O-ring replacing conventional flange sealing.

Dimensions and Materials

Body Materials: Options include grey cast iron (GG-25) and stainless steel (1.4404).
Dimensions: Detailed dimensions provided for various DN sizes, with specific piston diameters and actuator volumes.
Installation: Recommended vertical installation up to 45°; horizontal installation requires additional support to prevent bending stress.

Installation Guidelines
Ensure no bending stress occurs on the spindle, support bridges, piston rod, etc., to maintain proper functioning and tightness. Suitable supports or suspensions should be installed. Avoid hanging installation of the material slider.

Specifications
A table provides head loss (in bar) for different nominal diameters (DN) and corresponding flow rates (m³/h) for standard bore, with head loss values ranging from 0.2 to 1 bar for DN sizes from 80 to 300.

Compliance and Safety
The products are considered partly completed machinery under directive 2006/42/EC and must not be used until declared in conformity with the directive. Refer to the Declaration of Incorporation and assembly instructions.

Compressed Air Quality
Outlines maximum particles per m³, humidity (pressure dewpoint), and oil content according to ISO 8573.1 standards, with classes ranging from 1 to 6.
