FLOAT VALVE SUB

TECHNICAL SUMMARY

API standard drill pipe float valve is one of necessary tool for drilling, it consists of float valve sub and float valve, the main function are to prevent drill cuttings come into mud when connecting each joint and the bit bore block caused by back flow of silt.
Engineered with precision and designed to regulate fluid flow, our high-quality float valves ensure optimal performance and dependable sealing. Crafted from durable materials, these valves offer superior resistance to corrosion, abrasion, and harsh operating conditions. With their innovative design and advanced functionality, float valves play a vital role in preventing backflow, maintaining pressure control, and enhancing safety in oilfield operations. Trust in our float valve solutions to optimize fluid control, increase efficiency, and achieve smooth-running operations in your oilfield projects.
1. Plunger-type float valves:
The Model F is a plunger-type float valve that provides a positive instantaneous shut off, providing constant fluid control while drilling. The Model F is a reliable and economical selection under standard drilling operations.
2. Flapper-type float valves:
The Model G is a flapper-type float valve that, when opened, offers an unobstructed bore through the float valve. The uniquely designed flapper closes rapidly to prevent shavings from entering the drill string when circulation stops and also assists primary BOP equipment in maintaining internal pressure control. The valve will fully open when the first joint is raised from the hole, preventing pulling wet joints.
