Reliability of valve operation affects service life and ease of inspection and maintenance. In order topredict reliability, a sound valve design must be backed up by a stress analysis and functional qualification testing under critical operating conditions. Typical tests performed on our valves are shown here. > Top Left to right: Functional Cryogenic testing of a 24 150 Class Gate valveat -196԰C (-320F). Bottom Left to right: Functional Cryogenic testing of a 36Д Velan S.A.S.flanged butterfly valve at -196C(-320аF). 18 bar (260 PSI). Testing Testing > Testing of smallforged valves.Cycling...

2. A flexible retaining ring provides a complementary seating pressure on the disc. > The side entry design allows easy and quick in-line maintenance through the side cover with free access to the seat and disc for inspection or maintenance without disassembly of actuators. No special tools are required. 1. The seat contains aninternal inconel spring, an internal envelope in stainless and a copper alloy external envelope which is flexible and extends to the same seating arrangement between the flanges. > EASY MAINTENANCE FIRE SAFE STEM SEAL LIVE-LOADED GLAND BOLTING (for LNG applications)...

In 1990, during its 40th anniversaryyear, Velan embarked on an important new challenge: the creation and implementation of a Total Quality Management (TQM) program. The goal of the program is continuous improvement of all Velan products and services through teamwork, training and performance.During the last several years,more than 1000 Velan employees have completed a five-day training course in statistical process controls (SPC). An important component of total quality management, SPC uses statistical techniques to measure variation in industrial and administrative processes. By measuring...

1. DESIGN > All valves are designed to comply withthe requirements of ASME B16.34, theASME code and specials to customer requirements as applicable. 2. QUALITY ASSURANCE > Every step from procurement throughproduction, welding, assembly, testingand packaging is in accordance with written rules contained in QA manuals. (An ASME Section III manual for code valve production and an ISO 9001QA manual for all other production.) Velan's four North American plants are certified to IS0 9001 and Plants 1 and 2 have ASME NӔ stamp autho- rization, Plant 3 has a certificate ofaccreditation. Orders are...
