Hispeed External Chemical Hydraulic Valve is classified as an external self-closing stop valve and is widely used on DOT407 and 412 cargo tanks. This is a robust and proven valve that satisfies the many requirements of the chemical transportation industry. The 316 stainless steel construction with optional Hastelloy® overlay and replaceable Teflon™ seat make this valve a versatile and reliable workhorse for any fleet.This valve does NOT include a sacrificial shear section;therefore, the cargo tank must have adequate accident damage protection to shield the valve as specified in 49CFR §178.345-8.The hydraulic actuator has a ¼” NPT inlet port and is specifically designed to completely isolate hydraulic fluid from cargo tank and piping. Hydraulic leaks are contained in the piston cylinder and will drain to the exterior of the valve through the indicator weep holes as an alert for repair.Two indicator pins are located on the bottom of the piston cylinder and move in relation to the disc. The pins can be used as a push point to manually jack open the valve.
