CF8, CF3, CF8C, CF10; Duplex and Super Duplex stainless steel e. The signal words “WARNING” and “CAUTION” are defined as follows: Indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury. It is considered inherently fire-safe by virtue of the fact that its performance does not change during fire-safe simulation tests.
Our triple offset design completely eliminates any rubbing action of the sealing elements during the 90 degrees of rotation, positioning Vanessa as the ultimate process valve. This manual covers the use of the RCS in all modes. Every Vanessa Series 30,000 valve in basic configuration features a smoothly grinded seat with Stellite ® grade 21 weld overlay highly resistant to galling, abrasion, erosion and corrosion. A packing flushing deviceis usually added whenever the fluid involves high health & safety risks – through this connection a pressure chamber and/or a suction point can be created to eliminate or intercept any leakage. What is a Vanessa valve?
A metal seal ring in Duplex (as a minimum) and a highly wear-resistant Stellite® grade 21 seat ensure prolonged superior tightness. Emerson Manual Actuator Vanessa Series 30,000 Standard Triple Offset Valve with Manual Actuator The Vanessa Series 30,000 is a robust triple offset valve featuring an integral-to-body valve seat and optimized seating angles, that enables the Series vanessa valve 30000 manual 30,000 to handle isolation and process control through multiple functionalities. The one-piece shaftmaximizes robustness to a level which is not reachable with stub shafts commonly used with low pressure butterfly valves. A one-piece metal Solid Seal Ring (SSR)is chosen whenever the application may negatively affect the life of the standard laminated seal ring. Heavy duty bearings and thrust bearing are designed to withstand high pressure loads and wear. 3 Valve verification 1. Keep this manual in a convenient place for your valve operators’ easy access.

For further details on valve use and maintenance refer to Vanessa Series 30,000 Installation, Operation and Maintenance Manual (IOM). The materials chosen for sealing, coupled with precise machining, significantly contribute to extending the life of the valve. WC6, WC9, C5, C12; austenitic stainless steel e. The disc is not a sealing element, only a carrier. In addition, a dynamic spiral wound gasket ensures an adequate expansion and contraction of the seal ring during opening and closing. Bolted extended bonnet protects packing from cryogenic service temperatures. 1 Valve inspection the closed position to ensure that the seal ring 1 Carefully remove the valve from the in the disc is not damaged during installation.
Seal rings are easily interchangeable thanks to their self-centering ability and the presence of reference pins that simplify assembly. There are now over 300,000 Vanessa valves operating around the world. Check the operability of the valve by stroking it to “full open” and “full close”. In this safety manual, the signals to the RCS are defined in de-energized-to-safe configuration. Two-piece packing glandsenhance safety and reliability in terms of fugitive emissions over time. Standard reinforced, braide. Suggested orientation is with the valve shaft horizontal or inclined from.
The shaft to disc connectionis secured by keys (no pins) to optimize torque transmission without compromising shaft integrity. Top and bottom bearings can be protected from dirty or polymerizing/crystallizing medium by flushing deviceswhich create a barrier by means of a clean fluid injection, providing additional operational safety and reliability. A virtually maintenance-free valve with tightness, operability and torque demand unaffected by cryogenic conditions and severe temperature fluctuations Features Non-rubbing 90-degree rotation and metal-to-metal torque seating provide bi-directional zero leakage tightness to ISO 5208, ENand API 598. Drawings and dimensional tables illustrated on this datasheet represent just a selection from Vanessa&39;s much wider product range (see Series 30,000 technical datasheets). Vanessa Triple Offset Valve Series 30,000. Series 30,000 vanessa valve 30000 manual basic configuration is available with several options: 1. A Unique Quality Product that Delivers in Hundreds of Applications With over 300,000 Vanessa valves successfully installed worldwide on a wide range of applications, you don&39;t have to look further than Emerson for a proven solution to long-term positive isolation, on-off, flow control and emergency operations.
Serial numbers are stamped on each valve nameplate: these numbers must be referred to in any after sales/spare parts enquiries or orders. A live loaded mechanismminimizes the need to tighten the packing whenever the valve is used in heavy duty applications (including thermal cycling) or packing maintenance is not practical. Certified pilot valves per IEC 61508 Parts 1 and 2 are rated. Triple offset butterfly valves (TOV) have three separate offsets. Zero Leakage | Reduced Space | Lower Maintenance Costs y The Vanessa metal seated, torque seated, rotary valve offers many of the advantages of butterfly valves and gate valves combined. manual before handling, transportation, mounting, operation and maintenance of valves.
valve solutions that are widely used in the process control industry; individual 3-way pilot valves, manual reset valves, and redundant pilot valve systems. At least one of the two solenoid operated valves in the RCS has to be energized to prevent the block valve from moving to the safe state. The Vanessa Series 30,000 is an all metal valve complete with metal-to-metal sealing elements. What is Vanessa series 30,000 valve? Each of these solutions are proven in use as a pilot valve in critical applications and in safety instrumented systems. Moody has consistently supplied the U. Vanessa valves all share the same trim – a combination of optimized angles, and robust bearings and shafts.
It is considered INHERENTLY firesafe by virtue of the fact that its performance does not change during firesafe simulation tests. THE VANESSA ADVANTAGE VANESSA 30000 For over 45 years, J. The Vanessa valve is a quarter turn, metal seated, zero leakage* rotary process valve, a valve which has become the standard for quality, reliability and durability among process valves.
EXISTING VALVES WITH VANESSA SERIES 30,000 Replacing an existing valve can be a necessity but also a strategic choice.
