We manufacture and deliver high-quality spare parts for all Flowrox™ valves. Genuine parts ensure that they are certified and specifically suited for your process.
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.
Sleeve: robust heart of the pinch valve
Technologically advanced Flowrox sleeves guarantee high wear resistance, corrosion resistance, a trouble-free operation, and extended lifetime. Our sleeves are 100% tight.
Flowrox rubber sleeves are handmade layer by layer in a quality process covered by ISO 9001:2015 and ISO 14001:2015. Sleeve has a reinforced construction, making them the pressure retaining part of the valve. Standard Flowrox PV, PVE and PVG sleeves are equipped with opening tags to ensure full valve opening in all process conditions.
Several sleeve design options including a conical sleeve for control valves and a vacuum sleeve for negative pressure applications are available. Maintenance is easy as sleeve change requires no special tools.
To cover a wide range of applications, several rubber qualities are available:
Standard sleeve options
Other sleeve options
Sleeves for knife gate valves
The sleeve is a moulded part with a reinforcement steel ring integrated near the sealing area. The flange of the sleeve is reinforced with a load distribution ring to ensure even compression.
