Description
CAMTOP PT-RD Насос Through Rupture Disc Circulating Клапан | 15K PSI | DST Предохранительный клапан
5 inch (127.5 mm) & 3-7/8 inch
Product Overview
The CAMTOP PT-RD Насос Through Rupture Disc Safety Circulating Клапан is a pump-through rupture disc controlled safety valve and circulating valve. It functions as a single-cycle safety valve for end-of-test operations as a shut-off tool.
The PT-RD Safety Circulating Клапан can be converted to a PT-RD safety valve if the circulating ports are removed, or converted to a circulating valve by removing the valve mechanism and adding the circulating ports.
If placed above the gauge carrier, the PT-RD also acts as a backup shut-in tool for the final shut-in, minimizing wellbore storage during final pressure build-up.
