Cast Iron Ball Valve with Plate or Painting or Galvanized Surface Cast iron: cast iron is an iron-carbon alloy containing more than 2% carbon Cast iron can be divided into: 1, gray cast iron 2, white cast iron 3, malleable cast iron 4, nodular cast iron 5, vermicular cast iron 6, alloy cast iron Generally speaking, the cast iron valve we use is nodular cast iron, which is obtained by spheroidizing the molten iron of gray cast iron. The precipitated graphite is spherical, referred to as ductile iron. It has higher strength, better toughness and plasticity than ordinary gray cast iron visit our website:https://www.ss-castings.com/cast-iron-valv , e/cast-iron- valve.html

Precision casting internal thread globe valve Cencho Stainless Steel Valve The opening and closing part of the precision casting internal thread globe valve is a gate. The movement direction of the internal thread globe valve is perpendicular to the direction of the fluid. The precision casting internal thread globe valve can only be fully opened and closed, and cannot be adjusted or throttled. The internal thread globe valve has two sealing surfaces. The two sealing surfaces of the most commonly used mode  internal thread globe valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2 ° 52 'when the medium temperature is not high. The  internal thread globe valve of the wedge internal thread globe valve can be made as a whole, called a rigid gate; it can also be made as a  internal thread globe valve that can produce a small amount of deformation to improve its manufacturability and make up for the deviation of the sealing surface angle during processing. The board is called an elastic shutter. The stainless steel  internal thread globe valve material is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The representation method is: Z41H-16P.

Hot selling stainless steel 3 pcs 1/4~4 inch stainless steel 304/316 ball valve The three-piece ball valve is one of the most widely used valves in recent years. The three-piece internally threaded ball valve is a new type of ball valve with some unique advantages of its own structure. For example, the switch has no friction, and the seal is not easy to wear. , The opening and closing torque is small. In this way, the specifications of the equipped actuator can be reduced, and the multi-turn electric actuator can be used to adjust and strictly control the medium. The three-piece internally threaded ball valve is suitable for working conditions requiring strict shut-off in petroleum, chemical, urban water supply and drainage, etc. The internal thread ball valve switch is light, small in size, can be made into a large diameter, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often in a closed state, not easily eroded by the medium, and is widely used in various industries.

Stop Check Valve description The DOFUN stop check valve is mainly used in the pipeline which only allows the medium to flow in one direction and prevents the reverse flow. Under the action of the fluid pressure flowing in one direction, the valve disc opens; when the fluid flows in the opposite direction, the valve disc acts on the valve seat by the fluid pressure and the self weight of the valve disc, thus cutting off the flow. It can be used to prevent the backflow of medium on various pipelines of refrigeration system. . stop check valve can also be used as stop valve. The products are mainly divided into straight stop check valve and angle stop check valve. Applicable medium: R12, R22, R502, R134a, R404A, r507, R717, etc We are professional Stop Check Valve Manufacturer more @ https://www.refrigerationvalve.com/

angle stop valve description Stop Valve is mainly used to cut off or connect the pipeline, so that the system can operate normally. Therefore, it must be kept fully open or fully closed during use, and it is not allowed to be half open. Products are mainly divided into straight through stop valve and DOFUN angle stop valve. Applicable medium: R12, R22, R502, R134a, R404A, r507, R717, etc ShanDong DoFun Refrigeration Technology Co., Ltd. ( Hereinafter referred to as DOFUN) is located in LiaoCheng, an ancient canal capital with rich historical and cultural heritage as well as beautiful scenery.
