B/H/F Series Orifice Gate
Patented design concepts and application of highly specialized materials have produced a high quality yet economical valve especially designed for use in handling dry bulk materials. This valve is typically utilized in dilute phase pressure or vacuum systems or under atmospheric (gravity) conditions. This valve gets it’s name due to the fact that the slide plate has an orifice (opening) that, when the valve is opened, aligns with the openings in the top and bottom valve frame openings. It utilizes dynamically loaded polymer seals (pressure plates) and provides positive material and air flow shut off up to 15 PSIG. This valve has a proven track record of solving demanding material handling problems and difficult installation requirements.
