- Scope
- This standard specifies the marking rules for oil ports, bottom poles, control devices and electromagnets of control valves used in hydraulic transmission systems. It is especially suitable for valves with two or three ports to be developed. Unlike the current method of marking valve ports, the marking rules specified in Table 1 do not apply to components that have been standardized in GB 8100, GB 8089 and GB 8101. The marking rules stipulated in this standard are applicable to the oil port connected between two valves or the oil port connected between a valve and a pipe. This rule is therefore valid for both pipe-mounted and manifold-mounted valves.
