4” CHEMFLOW™ BITUMEN 90° pneumatic footvalve is designed to discharge hot bitumen from road tankers. Made of 304L 1.4307 stainless Steel, this product is designed with appropriate seals to work in a high temperature environment (250°C). The conical poppet with blades facilitates the opening in case of solidification of the bitumen. Time of discharge is improved due to the 40mm stroke. The footvalve can be manually operated in case of pneumatic failure.
