The Butt Weld (B4) check valve is a one piece body machined from bar stock, eliminating porosity concerns and providing uniform density for more consistent welds. Made to ASME/ANSI B16.25 for schedule 40 pipe, it carries rugged, dependable Check-All trim with a wide variety of seat materials and cracking pressures to choose from.
Note: Please take precautionary measures when welding to prevent heat build-up and possible damage to the valve seat.
