They are used for:

- noncorrosive fluids

- water

- steam

- oil

- petroleum and petroleum products

The steel flanged and welded swing check valves are the pipeline valves,

preventing automatically a working medium from the back flow.

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.

order specification:

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.

The swing check valves can be assembled in the horizontal pipeline.

The swing check valves are subjected to pressure tests according to the standard API 598 on strenght and tightness,

closure tightness with low pressure (on customer´s request), closure tightness with high pressure.

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.

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.

The swing check valves are supplied in the different material variants.

quality system:

testing:

MSA, a.s. executes the whole range of special tests which verify the properties of valves. They are as follow:

pressure testing

fire testing

testing on seal strenghtTest on seal strenght is executed with methan.

cycle testingCycle test is executed by 3000 cycles (open-close) with water.

hydrodynamic and aerodynamic testingMSA, a.s executes this test for the verification of hydropneumatic and aerodynamic properties.

operating testingOperating test is executed on all valves at MSA, a.s.

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.

All pressure tests are executed according to API 598, 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 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.

Operating test is executed on all valves at MSA, a.s.non-destructive testing

visual inspection

certification:

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.

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).

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.

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.

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.
