Buffer ring
 The buffer ring determines the lift of the valve plate. It clamps the discharge sealing ring on to the valve seat to guarantee frictionless guided movement. The curvature of the buffer ring is precisely engineered to define the discharge flow area.
The buffer ring must be shaped to minimize ring stresses at the maximum flow area. Local deformation and stresses will reduce reliability.
Valve ring
Like the valve plate, the valve ring is subject to extreme dynamic loads. It is laser cut from the same steel alloy.
 The valve ring and the buffer ring must fit perfectly together. The thickness and stiffness of the valve ring must be precisely adjusted to suit the dynamics of the valve.
Valve seat
The seat is made of a special steel alloy with extreme tensile strength so that the seat can be as thin as possible, minimizing the clearance volume. The flow area must maximize the valve efficiency. Advanced 3D models to simulate operating conditions and stresses provide essential information for optimizing the dimensions of the valve seat, while still maintaining adequate strength. There must be a good seal between the valve plates, and the seat must be airtight. This demands an extremely fine surface finish, and extreme hardness to provide resistance to wear.
The operating reliability and efficiency of the compressor depend on an ample flow area and minimal clearance in the valve.

Spring plate
The spring plate returns the valve to its seat after lift is released. It must distribute the springload evenly on the valve plate. It is made from high-quality heat-treated spring steel.
Close tolerances ensure equal force and deflection rates during operation. This is a critical factor in efficient and reliable valve dynamics.
Valve plate
The valve plate is the most vital part of the valve. As the sealing element, it moves constantly, absorbing the energy of impact and dissipating the stress. It is made of a high-quality steel alloy with the same extreme hardness as the valve seat.
A specialized polishing process removes all sharp edges to avoid local stress concentration under the high dynamic load. The sealing surface must be absolutely flat.
