Victaulic has expanded its Vic®-300 MasterSeal™ butterfly valve line with a stainless steel option. A cost-competitive alternative to flanged valves, the new grooved-end Series 461 stainless steel butterfly valve enables faster, easier installation while offering a bubble-tight seal, improved flow and extended service life.
The Series 461 valve features a patented seat design that seals equally on both sides of the valve. This feature assures full 360-degree sealing and minimizes long-term wear, resulting in a longer life expectancy than most conventional valves. The unique design of the offset disc and two-piece stem increases flow and reduces operating torque by up to 35 percent.
Featuring Victaulic OGS (Original Groove System) ends, the Series 461 is joined using Victaulic couplings, enabling quicker and easier installation and maintenance than flanged valves. The Series 461 is also lighter in weight than comparable flanged valves, further easing handling and installation.
For applications requiring compliance with the Reduction of Lead in Drinking Water Act, the Series 461 valve is NSF Certified in accordance with ANSI/NSF 61 for cold and hot potable water service and ANSI/NSF 372.
The Series 461 butterfly valve is designed for pressures ranging from full vacuum to 300 psi (2,065 kPa) and delivers bi-directional shut-off and dead-end capabilities to the full rated working pressure. The valve is available in 2- to 8-inch sizes (50 to 200 millimeters) with EPDM or nitrile seats; a standard ISO mounting flange to accept most gear and power actuators; and either a 10-position or lever-lock handle that may be configured for infinitely variable service with memory stop. The valve is pad-lockable for use with an appropriate lockout/tagout system, and may be locked either fully open or fully closed.
