4×4 Quick Clean Chemical Hydraulic Valve (Steam Jacketed)

Betts Quick Clean Chemical Hydraulic Valve with steam jacket body 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, a smooth tapered seat and a steam jacket body with two ¾” NPT fittings which allows for the valve to be heated for use with temperature sensitive products. 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.

Valve must not be subjected to rapid thermal shock which can cause damage to the valve or steam jacket body. Heating or cooling should be gradual and controlled. Caution should also be used to ensure liquid does not freeze in steam jacket.

See standard Quick Clean Valve page (Section 35 Page 7A) for additional details on actuator.
