Product Description

Introduction

Model "C" multi-circulating valve is a string inner pressure control, the cycle of multiple on-off circulating valve. The valve can be set at Open or Close position RIH. When it is Opened, allow for reverse circulation(normal circulating is limited). The valve working differential pressure is more than 50 Map.
Hydraulic Pressure can control it at open or close operation and It is easy confirm which position it’s? When the pumping the inner pressure in the inner tubing string is greater than 2 Mpa than annulus pressure and no longer increases, the valve will be closed after drain the pressure. And when the pressure arrived at 2 Mpa and keep rising to 5-6 Mpa means the valve will be in open position after drain inner pressure.
