Product Description

By-Pass Valve
During drilling operation, when a well kick takes place and bit bore is blocked, the by-pass valve can be opened to allow fluid circulation and well killing. Before drilling in a gas formation, the By-Pass Valve shall be located near or on the bit.

When well kick take place and pump pressure is too high or blocked, the following steps can be taken to open the By-Pass Valve 

• • Discharge Kelly and drop in a steel ball (or a Nylon ball) which is carried by tool;
  • Connect with Kelly;
  • Put ball into retainer by pump circulation;
  • When fluid is closed, the shear pin can be sheared off by adding 0.5~1.5MPa higher pump pressure than original pump pressure;

When ordering please specify:

• • O.D. of body;
  • Connection;
  • Pump pressure required to shear off pin (per customer requirement)
