FELUWA TopEntry Quick Change Valves (TEQS)

Easy Valve Repair

Even valves with very long design lives have to be replaced some day, and such replacement should be easy and fast. For this purpose, FELUWA has developed a Quick Change System. It maintains the typical linear flow of FELUWA valves and allows for safe and easy replacement of valve trims within minimum downtime. Valve assemblies are subject to hydraulic clamping and can be easily swiveled out for replacement of valve ball, guide and seat. Each part can be removed from the top. Changing times are less than 30 minutes, even for bigger valves (max. ball diameter = 300 mm).

Dependent on the pump duty, check valves are either specified as single or double ball, cone or plate valves. Big size double check valves of high-pressure pumps are additionally provided with newly developed FELUWA Quick Change system. Prior to fixing the check valves by locking screws, the hydraulically activated clamping mechanism is subject to axial pretension by means of a hand pump. Simple valve dismantling is achieved in reversed order.
