VANESSA 30000 Series Valve

The Vanessa 30,000 is an all metal valve complete with metal-to-metal sealing elements. It is considered inherently fire-safe by virtue of the fact that its performance does not change during fire-safe simulation tests. Triple offset butterfly valves (TOV) have three separate offsets. Two offsets are placed from the center while the third is on the seating surface which creates a cone type shape of the disc and seat. The Vanessa Series 30,000 valve, severe service version provides for unmatched tightness even when compared to soft seated designs. The tightness capability is generated by the radial compression of the seal as torque is applied to the valve shaft. The Vanessa 30,000 valve therefore provides shutoff regardless of the direction of flow or line pressure.

US Navy configurations conform to MIL-PRF-32307. Marine/Navy trim available with an aluminum bronze body, disc, and seat with Monel Shaft and seal ring. Vanessa is suitable for use in fireman isolation as well as many other applications where tight shut-off are required. Vanessa provides valuable space and weight saving over traditional gate valves and ball valves.
