The steel flanged and welded swing check valves are the pipeline valves, preventing automatically a working medium from the back flow. They are used for: - noncorrosive fluids - water - steam - oil - petroleum and petroleum products The operating parameters are in accordance with the standard ASME B 16.34. The application for other working mediums is necessary to discuss with the manufacturer. technical description: construction: Basic construction of swing check valve according to ASME B 16.34. Swing check valves flanged and welded, with unnarrowed flow rate, consists of body, cover, plate and arm. Seat is bolted or welded. he plate is seated on the sealing surface of seat that is placed on the arm that is turning on a pin of special hinge. Connecting flanges of flanged design are cast in the one whole with body. designed dimensions: The designed dimensions of standard design are stated in the table below. The designed and other dimensions correspond to the standard ASME B 16.10, the connecting dimensions of flanges correspond to the standard ASME B 16.5. material design: The swing check valves are supplied in the different material variants. assembly: The swing check valves can be assembled in the horizontal pipeline. testing: The swing check valves are subjected to pressure tests according to the standard API 59 on strenght and tightness, closure tightness with low pressure (on customer s request), closure tightness with high pressure. order specification: Data necessary in the order: type number, nominal diameter, pressure class, design (connection), body material, material of inner equipments, working parameters, acceptance tests, accompanying documentation.

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 59, API 600, API 6D and DIN 3230. 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 6755, part 2, for pressure class 150, 300, 600. testing on seal strenght Test on 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-55 for steel castings and according to order specifications. certification: Quality system of MSA, a.s. is based on the strict observation of 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.
