1 The globe valves are used as a closing valve for: - noncorrosive fluids - saturated steam - oil - air - petroleum and petroleum products The Characteristics of working conditions: pressure dependency on temperature according to ASME B technical description: construction: The construction of cast steel globe valves of MSA is in accordance with the standard API 600, BS A spindle has got an outer thread and is either rising rotative or rising non-rorative. The standard thread of spindle is ANSI B 1., type ACME. The spindle and gland packing space meet the requirements of API 600. A spindle is placed in the head of yoke cover firmly or on ball bearings. A cover joint is executed with the help of cover s and s. The globe valves has got cast (forged variably) plow that moves in the vertical direction to a sealing seat. The seats are ed or inserted and secured with a sealing weld around the flow circumference. The minimal thickness of overlay on the sealing surfaces of seat and plow is 1,6 mm, hardness depends on the type of overlay material. The operation is with a classical or impact handwheel or in combination with an angle gear box. The sealing of spindle si executed standardly with the plaited and pressed graphited rings. The properties of globe valve packings of MSA meet the requirements of the regulation Clean Air Act, Amendment from designed dimensions: Designed dimensions of standard design are stated in the table below. material design: The globe valves are supplied in the different material variants. assembly: The globe valves can be assembled into the pipeline in a random position, but the installation into the position with a vertical spindle axis is recommended. testing: The globe valves are subjected to pressure tests acccording to API 98 on strenght and tightness, tightness of backseat, closure tightness with low pressure ( if it is required in the order), closure tightness with high pressure. order specification: Data necessary for an order: type number, nominal diameter, pressure class, design (connection), type of operation, material of inner equipment, requested tests, accompanying documentation.

7 quality system: The whole manufacturing process is completely monitored and includes the following tests and inspections: acceptance inspections of all input materials and sub-deliveries, inspections of particular components in the course of manufacture, assembly testing, pressure testing, operating testing, non-destructive testing and final inspections of finished product. testing: MSA, a.s. executes the whole range of special tests which verify the properties of valves. They are as follow: pressure testing All pressure tests are executed according to API 98, API 600, API 6D and DIN MSA, a.s. also performs standardly the special tests according to API 6D. A criterium for acceptance is zero permeability. At the same time, MSA, a.s. executes standardly testing at full operating pressure by which a possible leakage could be detected in the body-cover joint, spindle, fittings or grease box etc. fire testing Fire test is executed at MSA, a.s. according to the standard API 6FD, API 607 and BS 67, part 2, for pressure class 10, 300 and 600. testing on seal strenght Test of seal strenght is executed with methan. cycle testing Cycle test is executed by 3000 cycles (open-close) with water. hydrodynamic and aerodynamic testing MSA, a.s executes this test for the verification of hydropneumatic and aerodynamic properties. operating testing Operating test is executed on all valves at MSA, a.s. non-destructive testing MSA, a.s. executes the non-destructive test in the own facilities and testing room. The non-destructive test includes RT, MT, UT or DP testing. The testing operators are higly qualified and certified according to EN 473 or STN-TC-1A. visual inspection Visual inspection is performed at all castings that are used for the valves of MSA, a.s. according to the quality directive MSS SP- for steel castings and according to order specifications. certification: Quality system of MSA, a.s. is certified according to EN ISO 9001:2000 and API Spec Q1 (Specification D - number 0239). research and development: Specialists of MSA, a.s. work on the development and research of new products and verify their properties as well such as: - suitability of applied material - strenght and rigidity of construction (FEM method) - operability with the emphasis on strenght and controlability - hydraulic and aerodynamic properties etc. New products are tested in the testing room of MSA, a.s. as well as in real operating conditions. The properties of product are observed during the whole service life and findings are applied in the development and production of new products.
