• Clamp butterfly valve connection

    Clamp butterfly valve is also called the sanitary quick-release butterfly valve, its connection way is composed of a precision casting clamp, a seal ring, two flat joints and a clamp butterfly valve. Clamp butterfly valve and clamp fittings can be used separately, but also complete sets of use. When used separately, the clamps are used primarily as connections for fixed piping or fixed pipe connections.

    Clamp butterfly valve rubber seals and valve plates are imported pieces to ensure the use of sanitary butterfly valve performance and service life.

    High precision CNC lathe fine valve body, to ensure a reliable interlock valve butterfly valve, replacing the rubber replaced by the use of performance can not guarantee the trouble.

    Clamp butterfly Valve Connection

    Stem mounted nylon bushings, reducing the friction and thus open flexible and easy.

    Steel pieces are made of stainless steel, rubber, food rubber, high-quality health.

    Sanitary valve body diameter and the pipeline diameter is same, when opened, valve plate is narrow and streamlined and the fluid is in the same direction with large flow and small resistance, no material accumulation.

  • Adamant valves aggressively promotes nitrogen in stainless steel tubes

    Since the beginning of July, Adamant valves engineering department chief engineer saw the stainless steel tube bore protection welding information from the network, they actively organized technicians, management personnel, welding experts to promote the stainless steel tube chamber nitrogen protection welding. 

    They carried out a scientific feasibility study, they believe that the total project pipeline is 110,000-inch diameter, a total of stainless steel welding is more than 60,000 inch diameter, is up to 55% of the total welding volume, and pipeline materials are suitable for the use of bore Nitrogen protection welding, in terms of welding quality, the project cost accounting have priority over the traditional argon-filled welding process.

    For this project the organization, all the welding operators on the stainless steel tube chamber and sanitary valves nitrogen protection welding technology need a special training, engaged in the welding operation for many years, with slide on the stainless steel tube nitrogen protection welding technical requirements and precautions, the production pass rate is 98%; Currently, the construction Engineering Project Department is using large area of stainless steel tube nitrogen protection welding.


    “Stainless steel tube nitrogen protection welding 'for soup' and argon welding protection in the technical requirements are not very different, not only the workers easy to accept, but also to ensure the welding speed! "the welder said.

  • The advantages of sanitary manual butterfly valve:

    1, butterfly valve rubber seals and valve plates are imported pieces to ensure the use of hard sealed butterfly valve performance and service life.

    2, Using high-precision CNC lathe fine body valve to ensure a reliable interchangeability of the butterfly valve, replacing the use and performance of the rubber which can not guarantee trouble

    3, the stem inlaid nylon sleeve, reducing the friction and thus open flexible and easy.

    4, steel pieces are made of stainless steel, rubber, rubber food, high-quality health.

    5, the valve body and the pipeline diameter, opening a narrow and streamlined valve plate and the fluid in the same direction, large flow and resistance, no material accumulation.

    6, the handle pull type , can withstand greater operating torque, not easy to pull off.

    7, opening and closing range of 0 ~ 90 degrees, can be fixed at every 15 degrees position, with adjustable, and open and close quickly, easy to operate.

    8, the sanitary valve body are removable connection, simple structure, easy maintenance.

    9, modeling is beautiful, surface is bright without sticky dust, no burr hand.

    10, A rigorous strength and sealing test to ensure quality.

    11, Not less than 30,000 times the fatigue life test to ensure its life of sampling.

    Sanitary Butterfly valve refers to the closure for the disc, rotating around the valve shaft to achieve the opening and closing of a valve, cut off the main pipe and cut with. Butterfly valve opening and closing pieces is a disc-shaped butterfly plate, the valve body around its own axis of rotation, so as to achieve the purpose of opening and closing or regulation. Butterfly valve is fully open to full close is usually less than 90 °, butterfly valve and butterfly rod itself has no self-locking ability, in order to disc positioning, to install the worm reducer stem. The use of worm reducer, not only can make the butterfly plate has a self-locking ability, so that the butterfly plate stop at any position, but also improve the operational performance of the valve.
