Põhitekst
This document specifies requirements and acceptance criteria for type testing, in compliance with design conditions, of metallic butterfly and ball valves used for isolating services for all industrial applications, and serves to validate the product design over 205 cycles. This document excludes testing for safety devices, control valves, thermoplastics valves, and valves for water supply for human consumption and sewage (e.g. the EN 1074 series). This document defines the procedure for extending the qualification of the tested valve to untested sizes and pressure designations of the same product range. The purpose of this type test is to validate the seat performance within manufacturer given pressure/temperature rating, provided by the manufacturer’s technical documentation of the product. This type test verifies torque requirements and the maximum allowable stem torque (MAST), as given in the manufacturer's technical documentation. This type test validates the durability of seat performance and operating torque through mechanical and thermal cycles.
