How about the price of the screw globe valve What is the approximate price of the globe valve

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, Su Yan, 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 the user's stove.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are changing rapidly, and the rankings may vary by time and region. For the latest ranking information, it is recommended to refer to industry reports, professional institutions or market research data for more detailed and accurate information.

The stem axis of the threaded globe valve is perpendicular to the sealing surface of the seat. The relatively short opening or closing stroke of the stem and the very reliable shut-off action make this valve ideal for use as a shut-off or adjustment and throttling of the medium. Once the globe valve is in the open state, there is no longer contact between its valve seat and the sealing surface of the valve disc, so the mechanical wear of its sealing surface is small, because the valve seat and disc of most of the globe valves are relatively easy to repair or replace the sealing elements without removing the entire valve from the pipeline, which is very suitable for the occasion that the valve and the pipeline are welded into one.

The flow direction of the medium through these valves changes, so the flow resistance of the globe valve is higher than that of other valves. This type of valve should generally be installed horizontally in the pipeline.

Commonly used globe valves are as follows:

1) Flange globe valve.

2) Angle globe valve; In an angle globe valve, the fluid only needs to change direction once, resulting in a smaller pressure drop through this valve than a conventional globe valve.

3) DC shut-off valve; In a flow-through or Y-shaped globe valve, the flow channel of the valve body is inclined to the main channel, so that the degree of damage to the flow state is smaller than that of the conventional globe valve, so the pressure loss through the valve is correspondingly smaller.

4) Piston globe valve: This form of globe valve is a variant of the conventional globe valve. In this valve, the disc and seat are usually designed based on the plunger principle.

The disc is ground into a plunger connected to the stem, and the seal is achieved by two elastic seals that are sleeved over the plunger. The two elastomeric seals are separated by a collar and the seals around the plunger are pressed firmly by a load applied to the bonnet by the bonnet nut. Replaceable seals can be made of a wide variety of materials, and the valve is mainly used for "on" or "off", but is available with a special form of plunger or special collar that can also be used to regulate the flow rate.

Features of threaded globe valves.

1) The structure is simpler than that of gate valves, and it is more convenient to manufacture and maintain.

2) The sealing surface is not easy to wear and abrasion, the sealing performance is good, there is no relative sliding between the valve disc and the sealing surface of the valve body when opening and closing, so the wear and abrasion are not serious, the sealing performance is good, and the service life is long.

3) When opening and closing, the stroke of the valve disc is small, so the height of the globe valve is smaller than that of the gate valve, but the structural length is longer than that of the gate valve.

4) The opening and closing torque is large, the opening and closing is more laborious, and the opening and closing time is the principal.

5) The fluid resistance is large, because the medium channel in the valve body is tortuous, the fluid resistance is large, and the power consumption is large.

6) When the nominal pressure is 16MPa, the medium flows upwards from the bottom of the valve disc; When the nominal pressure is PN 20MPa, counterflow is generally adopted, and the medium flows down from above the disc to increase the seal energy. When in use, the globe valve medium can only flow in one direction, and the flow direction cannot be changed.

7) When fully open, the disc is often eroded.

Once the disc of the threaded interception stop valve is in the open state, its valve seat and the sealing surface of the valve and the volcanic valve are no longer in contact, and have a very reliable shut-off action, which is very suitable for the use of medium cut-off or adjustment and throttling.

(1) The ball valve has simple structure, small size, light weight, small flow resistance and good energy-saving effect. When the medium flows through the gate valve, it is equivalent to flowing through a straight pipeline, and the fluid resistance of the gate valve is the least among all types of valves.

2) The direction of fluid inflow and outflow of the valve can be arbitrarily selected, with two-way effect.

3) Both horizontal and vertical pipes can be installed.

4) Easy to operate, quick switch, switch can be realized by turning the handwheel a few times.

5) The valve has good anti-leakage effect and long service life.

Performance characteristics 1, good opening and closing and switching performance.

2. Good sealing and flow resistance.

3. The appearance structure and smoothness are high, and the quality is very perfect!
