Constructive characteristics:

The valves are seat guide type with low resistance on the fluid flow. The valve gasket is symetric with two faces which can be reversed and used further after the first workface has been worn.
The valve seat is mounted in the hydraulic body by pressing on the cone and seals against this metal-to-metal. The seat and the valve disk are hardened by carburation and have high-resistance against wear.
The valve spring provides a proper steadiness of the valve during operation.

Main materials

  • Disk and seat: forged alloy steel
  • Gasket: rubber with special characteristics
