Technical data

Piping should be properly supported to
prevent any strain on bursting disk mounting.
Be careful not to puncture bursting disk when
thread protector is removed.

Notes: 1). Dual relief valve consists of one three-way shut off valve and two single relief valves. The valve configuration will not allow both valves to be shut off at
the same time, and valves are sized such that each relief valve has sufficient discharge capacity when used alone. This permits safe removal of either relief
valve for repair or replacement, while maintaining vessel protection.
