Pneumatic part-turn actuators for industrial valves – Basic requirements. To qualify a range of actuators, of the same design and of the same action, manufactured under the same process and from the same or equivalent materials, the type tests may be carried out on a limited number of sizes by applying the following rule: The shaft shall have a slot and a threaded hole according to Figure 4.
To qualify a range of actuators, of the same design and of the same action, manufactured under the same process and from the same or equivalent materials, the type tests may be carried out on a limited number of sizes eh applying the following rule: If the slot is used as a position indicator it shall be parallel to the pipe axis when the valve is open. Maximum allowable stem torque limitation MAST.
Buildings or areas with almost permanent condensation and with high pollution. The manual operating forces shall be in accordance with EN The position, location, orientation and form of the pressure connections shall be established by the manufacturer.
Tabulation method for steel valve shells. The relationship between air volume V and dimensions of connections “2” and “4” are given as guidelines. Classification system and qualification procedures for type testing of valves. Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service.
The relationship between air volume V and dimensions of mounting levels 1 and 2 are given as guidelines. NOTE 2 Table 2 may be used to define the corrosion category in order to help the actuator manufacturers to define the surface treatment for corrosion protection.
