Description
CAMTOP PT-RD Pump Through Rupture Disc Circulating Valve | 15K PSI | DST Safety Valve
5 inch (127.5 mm) & 3-7/8 inch
Product Overview
The CAMTOP PT-RD Pump Through Rupture Disc Safety Circulating Valve 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 Valve 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.

CAMTOP PT-RD Pump Through Rupture Disc Circulating Valve — 5 inch, 15,000 psi, alloy steel, DST safety valve for cased hole drill stem testing
Key Features
- Dual Function Design: Functions as both a safety valve and circulating valve; can be converted between configurations by adding or removing components
- Pump Through Capability: Pump-through rupture disc controlled operation enables single-cycle safety shut-off at end of test operations
- Backup Shut-In Tool: When placed above the gauge carrier, acts as a backup shut-in tool for final shut-in, minimizing wellbore storage during pressure build-up
- High Pressure Rating: Rated to 15,000 psi (105 MPa) working pressure with 149 MPa internal pressure strength
- H2S Sour Service: Compliant with NACE MR0175 for H2S-containing environments above 175F
- Shear Pin System: Adjustable shear pin system with up to 18 pins, single shear pin value 5.2 +/- 0.3 MPa for precise pressure control
- High Tensile Strength: 2431 KN tensile strength and 70 KN.m torque strength for demanding DST operations
- Alloy Steel Construction: Manufactured from high-strength alloy steel for reliable downhole performance
