RV Series Drop-Through Rotary Valves
(20)
RV Rotary Valves have been designed for universal use. They are ideally suited to control delivery or discharge of powder or granular materials from silos, hoppers, pneumatic conveying systems, bag filters and centrifugal separators. Their strong and compact design makes it a simple matter to access the internal working parts. Different types are available according to the required flow rates.
RV Valves have been developed for maximum versatility in application. They are suitable for controlled discharging and feeding of powdery or granular materials from silos, hoppers, pneumatic conveying systems, bag filter houses, or cyclones.
Performance and Technical Features:
• Feed rates from 2.2 to 19.5 litres per revolution (0.08 to 0.7 cu ft per revolution)
• Different drives for different rotation speeds
• Maximum differential pressure: 0.3 bar (4.4 PSI)
• Compatible with other WAMGROUP® equipment thanks to WAM® standard flanges
• Various materials and treatments available according to product handled
• Robust and compact design
• Easy access to all internal mechanical components

RVC Drop-Through Rotary Valves
RVS Blow-Through Rotary Valves consist of a tubular cast iron or stainless steel casing, a horizontally mounted rotor with a certain number of oblique V-shaped cross section compartments, a drive unit and a casing cover at each end.
Two compartments at a time of the continuously turning rotor are filled up with material through the inlet at the top of the Rotary Valve. After less than half a turn the material falls through the bottom opening into an air stream passing through a pneumatic conveying pipeline connected with the bottom part of the Rotary Valve.
Performance and Technical Features:
• Available in ATEX zone 22 version
• Robust and compact design
• Rotor: integral with beveled blades, with scrapers (Viton®, Vulkolan, Teflon®)
• Fixed rotor speed: 10 / 20 / 30 r.p.m.
• Variable rotor speed: 4 ¿ 22 r.p.m.
• Rotor surface treatment: nickel plating, Teflon® coating, hardened blades
• Casing: cast iron or 304 / 316 stainles steel
• Casing surface treatment: nickel plating, Teflon® coating
• Drives: direct with gear motor, with variable speed gear motor, coaxial with chain transmission, bare shafted without drive
• Easy access to all internal mechanical parts
