GB/T 17213的本部分规定了按照GB/T 1 7213其他各部分制造的控制阀的检验和例行试验要求。自本部分实施起，检验和例行试验要求应取自本部分，连同4．1所要求的任何附加资料或买方的实施规程一起执行。GB/T 17213的本部分不适用于在放射性工作环境、防火试验环境或其他危险工作环境中使用的各类控制阀。如果涉及危险工作环境的有关标准与本部分相矛盾时，应以该标准为准。本部分仅适用于压力等级不超过PN420(2500级)的控制阀。对执行机构的要求仪适用于气动执行机构。

Scope

This part of GB/T 17213 specifies inspection and routine test requirements for control valves manufactured in accordance with other parts of GB/T 17213. From the implementation of this section, the inspection and routine test requirements shall be taken from this section, together with any additional information required by 4.1 or the purchaser's implementation procedures. This part of GB/T 17213 does not apply to various control valves used in radioactive working environments, fire test environments or other hazardous working environments. If the relevant standards involving hazardous working environments conflict with this part, the standards shall prevail. This part is only applicable to control valves whose pressure rating does not exceed PN420 (Class 2500). The requirements for actuators apply only to pneumatic actuators.
