Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Chaoda, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

Z -- indicates the gate valve (the initial letter of ZHA) 4--- is the form of connection, indicating the flange connection.

1--- The structural form indicates that the 40--- nominal pressure of the open rod wedge rigid single gate gate valve H --- sealing surface surfacing iron-based cemented carbide (the first letter of HE of alloy steel) is 40 kg, that is, the maximum working pressure of PN10 below 250 degrees Celsius is 40 kg.

The material is cast carbon steel.

There are two differences:

1. The sealing material of Z41Y is cemented carbide; The Z41H sealing surface is alloy steel.

2. Gate valve (gate valve) is an opening and closing part ram, the direction of movement of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, and the parameters of the door are different, usually 5°, and 2°52' when the medium temperature is not high.

To improve its manufacturability and make up for the deviation of the sealing surface angle in the processing process, this kind of ram is called elastic ram.

1. The ram structure is different

Z40 is a wedge-type elastic ram;

Z41 is a single ram rigid wedge ram.

2. The working principle is different

The opening and closing parts of the Z40 gate valve are the ram, the direction of movement of the ram is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The ram has two sealing surfaces, and the most commonly used mode gate valve has two sealing surfaces forming a wedge, and the wedge angle varies with the valve parameters, usually 5°, and 2°52 when the medium temperature is not high'。

Z41 gate valve is a valve that relies on the gate plate as the opening and closing part and moves vertically along the axis of the valve seat to achieve the opening and closing action. The main advantages of the gate valve are smooth flow path, low fluid resistance, and small opening and closing torque;

Handwheels, handles and transmission mechanisms are not allowed to be used for lifting, and collisions are strictly prohibited. The double gate valve should be installed vertically (i.e., the stem is in a vertical position and the handwheel is at the top). Gate valves with bypass valves should be opened before opening (to balance the pressure difference between the inlet and outlet and reduce the opening force).

The gate valve with transmission mechanism shall be installed according to the provisions of the product instruction manual.

Z41H-16C is a model of flanged open rod gate valve made of cast steel.

Among them, Z represents the gate valve, 4 represents the flange connection, 1 represents the open rod structure, H represents the stainless steel seal, 16 represents the nominal pressure of 16 kg, and C represents the valve body material cast steel.

Z41H-16C gate valve is a single gate valve, the gate rises and opens, the gate falls and closes, and can be used as a general valve for pipeline switching.

Z stands for - Gate Valve, 4 stands for Flange, 1 stands for Straight Structure, H stands for - Alloy Seal, 16 stands for - Pressure 16 kg or, C stands for - The body material is WCB, carbon steel or cast steel, and DN stands for Caliber.

Meaning of valve Z41H-16C.

Meaning of valve Z41H-16C pro! Hello, happy to answer your <>. The meaning of pro-valve Z41H-16C is to represent the single gate valve represents the single gate valve, when the gate rises and opens, the gate will automatically fall and close, mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems, in order to transport high viscosity media that will solidify at room temperature.

Among them, Z represents the gate valve, 4 represents the flange, 1 represents the straight-through structure, H represents the alloy seal, 16 represents the pressure of 16 kg or, and C represents the valve body made of carbon steel or cast steel. 1. What is Z41H16C This product has good thermal insulation and cold insulation characteristics, and the diameter of the valve is consistent with the pipe diameter, and at the same time, it can effectively reduce the heat loss of the medium in the pipeline. It is mainly used in petroleum, chemical, metallurgy, pharmaceutical, food and other systems to transport high-viscosity media that will solidify at room temperature.

Due to the integral structure, the insulation ball valve is smaller than the general ball valve, lighter in weight, and no leakage, good sealing performance, and the jacket is welded with carbon steel pipe and is more pressure-resistant and firm than casting. 2. What does the gate valve model represent According to China's "Valve Model Preparation Method", the gate valve model is generally composed of 7 units, taking Z861Y-200I as an example, Z is 1 unit, representing the type of gate valve; 8 is 2 units, which represents the driving mode of the gate valve; 6 is 3 units, which represents the connection form of the gate valve; 1 is 4 units, which represent the structural form of the gate valve; Y is the 5 unit, which represents the sealing surface of the gate valve as well as the material of the lining; 200 is 6 units, which represents nominal pressure and working pressure; i is the 7 unit, which represents the material of the gate valve. For example, model Z861Y-200i, Z is 1 unit, 8 is 2 units, 6 is 3 units, 1 is 4 units, Y is 5 units, 200 is 6 units, and I is 7 units.

Do you have any other questions?

Z41Y seal material is cemented carbide Z41H seal face is alloy steel.

Y means with cemented carbide, and H is sealed directly with the body material. The rest makes no difference.
