order specification:
The globe valves can be assembled into the pipeline in a random position, but the installation into the position with avertical spindle axis is recommended.
The globe valves are subjected to pressure tests acccording to API 598 on strenght and tightness, tightness ofbackseat, closure tightness with low pressure ( if it is required in the order), closure tightness with high pressure.
The construction of cast steel globe valves of MSA is in accordance with the standard API 600, BS 18 73.A spindle has got an outer thread and is either rising rotative or rising non-rorative. The standard thread of spindle isANSI B 1.5, type ACME. The spindle and gland packing space meet the requirements of API 600. A spindle nut isplaced in the head of yoke cover firmly or on ball bearings. A cover joint is executed with the help of cover bolts andnuts.The globe valves has got cast (forged variably) plow that moves in the vertical direction to a sealing seat. The seatsare bolted or inserted and secured with a sealing weld around the flow circumference. The minimal thickness ofoverlay 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 globevalve packings of MSA meet the requirements of the regulation Clean Air Act, Amendment from 1990.
The globe valves are supplied in the different material variants.
Designed dimensions of standard design are stated in the table below.
Data necessary for an order: type number, nominal diameter, pressure class, design (connection), type of operation,Data necessary for an order: type number, nominal diameter, pressure class, design (connection), type of operation,material of inner equipment, requested tests, accompanying documentation.

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 of 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: acceptanceinspections of all input materials and sub-deliveries, inspections of particular components in the course of manufacture, assemblytesting, pressure testing, operating testing, non-destructive testing and final inspections of finished product.
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 and 600.
All pressure tests are executed according to API 598, API 600, API 6D and DIN 3230. MSA, a.s. also performs standardlythe special tests according to API 6D. A criterium for acceptance is zero permeability. At the same time, MSA, a.s. executesstandardly testing at full operating pressure by which a possible leakage could be detected in the body-cover joint, spindle,fittings or grease box etc.
Operating test is executed on all valves at MSA, a.s.non-destructive testing
visual inspection
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 areobserved during the whole service life and findings are applied in the development and production of new products.
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 is performed at all castings that are used for the valves of MSA, a.s. according to the quality directive MSSSP-55 for steel castings and according to order specifications.
