Ventil Orbit 24 Series: Valve Grinding & Lapping Machines

"The ORBIT 24 is a robust, but lightweight grinding and lapping machine for ‘in-situ’ or ‘in-shop’ repair of damaged valve seats. The unique set up and construction makes the versatile ORBIT 24 suitable for all sorts of vertical seats (Gate-, Parallel slide-, Check Valves) and horizontal mounted seats (Globe- and Safety valves) in the range 6-24”. The ORBIT 24 is suitable and equipped for grinding and lapping the faces on both the Gate valve seats and wedge.

Both seats inside the valve body are quickly machined in one setting of the mounting bracket. The standard included Gate valve wedge bracket allows you to accurately machine both faces of the wedge. Within seconds the ORBIT 24 is prepared for machining the flat seats of both Gate-, Parallel Slide, Globe and Safety valves. The ball joint construction in the arm ensures a very easy alignment and accurate control of the force. The unique orbital, - mechanical driven grinding head results in a very high material removal rate and extreme flatness accuracy.

The ORBIT 24 is equipped with two different grinding heads and three sets of different lengths of grinding arms to cover the whole range. The grinding heads are mechanically driven by an internal gearing system that rotates the wheels at the same speed producing the perfect cross hatch machining pattern. This orbital lapping design assures the highest material removal rate with the highest flatness accuracy. Absolute flat grinding is guaranteed by the mechanical drive having the same speed on the inside and outside of the seat.
