Quick Clean Chemical Hydraulic Valve


[su_youtube url=””]

Betts Quick Clean Chemical Hydraulic Valve is classified as an internal self-closing stop valve and is widely used on DOT407 and 412 cargo tanks.  The key features of the Quick Clean are a rapid removal spring housing assembly, a self-contained hydraulic actuator and a valve body with a smooth tapered seat.  The 316-stainless body with an optional Hastelloy® overlay seat and replaceable Teflon™ encapsulated main seal make this a versatile and proven valve that satisfies the many requirements of the chemical transportation industry.

A sacrificial shear section is standard with the Quick Clean Valve and meets the requirements of 49CFR §178.345-8 as tested and verified per TTMA RP84.

The hydraulic actuator has a ¼” NPT inlet port and is a self-contained assembly which can conveniently be replaced without removing the valve from the cargo tank.  The actuator completely isolates hydraulic fluid from cargo tank and piping.  Hydraulic leaks are contained in the actuator assembly and will drain to the exterior of the valve through weep holes as an alert for repair.  An indicator rod is located on the bottom of the actuator and can be used as a push point to manually jack open the valve.
