The new TeraValve™ abrasive metering valve is revolutionary in its ability to provide high performance, pressure hold blasting at a cost effective price point. The TeraValve™ is diaphragm activated, simplifying overall operation and maintenance. The new Schmidt extended life (XL™) technology is incorporated for durability and long life, even when the valve is used with harsh abrasives. Its compact size fits easily onto low clearance blast pots or blast cabinets without modification, making it easy to convert automatic blowdown pots to a more efficient and productive pressure hold system.
