Flowrox™ heavy duty pinch valves
Pinch valves for shut-off and control applications
Flowrox PV, PVE and PVE/S heavy duty pinch valves are designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the center line. Bubble tight shut-off is provided even if solids have built up on the sleeve wall.
Flowrox PVG and PVEG pinch valves are robust and cost effective with simple, single-sided closing mechanism. PVG valve has a strong valve body and opening tags in the sleeve as a standard. PVEG valve has a corrosion resistant and light-weight plastic body. Through the reliability and structure, both kinds of valves offer substantial savings based on improved performance, long service lifetime and low total cost of ownership. Flowrox PVG and PVEG valves are ideal for low cycle applications involving abrasion, corrosion and aggressive slurries
Heavy duty slurry knife gate valve isolates flow even in the most demanding process conditions. The bi-directional flow tolerates backflow and elastomer sleeves on both sides of the gate provide tight shut off. Flowrox knife gate valve follows the concept of the ease of maintenance. The valve body is cast in one piece which eliminates the need for sealing between the body halves. Load distribution ring is integrated into the valve sleeves. The valve contains only two service parts; ring sleeves and secondary seal.
Main spare parts for valves are rubber sleeves. Elastic sleeve is the core of the Flowrox valve. It is the only part in contact with the process medium. Maintenance is easy as sleeve change requires no special tools. Technologically advanced Flowrox rubber sleeves guarantee high wear and corrosion resistance, a trouble-free operation, and extended lifetime. Our sleeves are 100% tight. Standard Flowrox PV, PVE and PVG sleeves are equipped with opening tags to ensure full valve opening in all process conditions.
