J48KH

The J48KH is a special version of the highly versatile and well proven J48K pressure relief valve. The J48KH has a higher inlet pressure rating and incorporates the spring adjustment mechanism of the high pressure J48 regulator.
The J48KH high pressure relief valve guards against excess pressure. The valve is fully automatic in operation and resets when the pressure falls below the pre-set value.
The relief pressure can be easily and accurately adjusted by turning the spring adjusting stem located under the top cap. The setting is maintained by a lock nut. The design of this mechanism provides virtually frictionless adjustment and eliminates "spring wind up".
The complete spring adjustment mechanism can be removed easily for maintenance and spring changes. If required the units can be supplied factory set with a security seal at extra cost.
