Peculiarity: 1, it uses double lever mechanical design principle and the whole stainless steel structure. The use of life will last more than ten years. 2, the packing material of the ball is waterproof bubble 3, have the automatic adjustment function. Size and weight depand on the demands of yours.

It consists of a valve connected to a hollow sealed float by means of a lever, mounted near the top of the tank. The float is often ball-shaped. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; once it rises to a pre-set level, the mechanism forces the lever to close the valve and shut off the water flow.

Drill pipe float valves, or non-return valves, are downhole safety valves that create barriers to prevent unwanted flow of fluids up the drill string. The float valve locks down the flow of fluids while the crew at the rigfloor is making or breaking connections. Specifying the optimum drill pipe float valve for oil and gas projects is critical - the different valve types extend further than a simple split between the F-type plunger valves and the G-type flapper valves.

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. 1.1 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. 1.2 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.

Description: Float valve is one of necessary tool for oil 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. When the well blowout or kick, the valve cover of float valve turn off the bore automatically, it will prevent well blowout accident. The working pressure of float valve is supposed to be 5000psi or 10000psi. Float valve sub has two types:

100X diaphragm type remote control float valve has many kinds of function and is installed at the inlet of pool or water tower, when the water-level reach the setting level, the main valve closes by the float pilot valve¡¯s control and stop supplying water, when the water-level comes down, the main valve opens by the float pilot valve¡¯s control and supply water to the pool. 100X remote control float valve can control the water-level of pool precisely and is not interrupted by the pressure. 100X remote control float valve can be installed freely according to the height of pool and using space. It is easy to maintain, to commission and to inspect. This kind of valve is reliable on sealing and it¡¯s life is very long. Diaphragm type valve is reliable and it¡¯s strength is high and it moves quickly and it is suitable for pipeline DN450 mm or less. For DN500 mm or more, piston type valve is advised to be chosen.
