The Rhinoflex- KWIKCHANGE™ Pinch Valves are used in the most demanding abrasive and corrosive and aggressive applications; typically slurries and dry powder transfer usually encountered in mineral processing, pulp and paper, effluent treatment, water and waste water power generation, steel and cement production, and many other difficult applications. These valves can be used for ON-OFF and or Modulating and control applications.
The Rhinoflex- KWIKCHANGE™ Pinch Valve was developed alongside our other Full-Frame, and Enclosed Body models, to compliment and complete the range of pinch valve options we have to offer. With our other range of Pinch Valves, a sleeve change-over requires the removal of the valve from the pipeline and a full dis-assemble to replace the sleeve. The KWIKCHANGE™ is a simple design that allows a fast sleeve change-over, WITHOUT REMOVING THE VALVE FROM THE PIPELINE. This will enable all the pneumatic or electric actuator and control automation to remain at the same calibration and settings as previously used, and take a fraction of the time to do a sleeve changeover, and don’t require any haulage equipment like other pinch valves.
The Rhinoflex-KWIKCHANGE™ Pinch Valves consists of fabricated body of carbon or stainless steel, and is operated mechanically with centre-line closing of two pinch bars, and offers 100% drip tight closure even on suspended solids. The standard Rhinoflex sleeve is the heart of our pinch valves and is the only wetted part in contact with the flow medium. These are FULL-BORE, Bi-Directional, self-cleaning with each cycle, extremely wear resistant sleeves that will not clog, jam or build-up.
The KWIKCHANGE – PINCH VALVE by RHINOFLEX is specially designed and engineered to REPLACE STANDARD DIAPHRAGM VALVES, and has the SAME FACE TO FACE DIMENSION (BS5156), as the diaphragm valve. This model was created because, we found that industry was demanding a longer lasting valve, with higher-pressure ratings to replace the diaphragm valve, with easier actuation, in the applications that diaphragm valves are used.
With the invention of the KWIKCHANGE, we guarantee that these valves will outperform any diaphragm valve, and is more cost effective to maintain, and is much more efficient in performance being a simple trouble free valve. This also has a KWIKCHANGE featured field replaceable sleeve, which has a chunky and thick wall, and gives much more wear life that the standard Diaphragm valve. The full bore of the sleeve, offers straight through flow, with no cavities or dead zones, for slurry to gather, and also assist in minimum head loss and turbulence. The KWIKCHANGE field replaceable sleeve is the ONLY wetted part, and will self-clean, every time the valve opens and closes and any build-up will flake off and flow away with the media. It is a simple valve, with very easy repair and replaceable options.
The KWIKCHANGE– PINCH VALVE is bi-directional and offers drop tight shut off, even on suspended solids. These are available in pressures up to 10-40 bar across the size range of 50mm to 600mm. All standard flange drilling patterns like ANSI, TAB D/E, DIN, etc. are available, with a wide selection of elastomers to choose from, depending upon the application.
