Features: BSPP male bottom inlet and a BSPT female side outlet. Dome top. Relief pressure can be set between 0.5 and 20.7 bar. Particularly suitable for most liquid applications where a ‘small’ discharge often prevents the safe pressure in a system being exceeded and saturated steam, gas and vapour applications where a low discharge is suitable. Other typical applications include vented and unvented systems, saturated steam boilers, pump, pipelines and vessel protection. TFM or viton seat options are available on request.
