Product Description

Porduct Name:	DIN Carbon Steel Flange Globe Valve
Material:	Carbon steel
Pressure:	PN40
Size range:	DN15-DN300
End Connection:	Flange
Mode of operation:	Manual

  The globe valve,also called the closure dorr,is one of the most widely used valve,and its popularity is due to the small friction between the sealing surfaces during the opening and closing process,relatively durable,opening height is not large,easy to manufacture,convenient maintenance,not only suitable for low and medium pressure,but also suitable for high pressure.The closing principle of the globe valve is to rely on the pressure of the valve lever to make the sealing surface of the valve disc closely fit the sealing surface of the valve seat,blocking medium.
  The valve plays an improtant role in cutting off and throttling the medium in the pipeline where it is located,and the globe valve is a very important cut-off valve.It is sealed by applying torque to the stem,which exerts pressure on the disc in an axial direction.The sealing surface of the valve disc is closely fitted to the sealing surface of the seat to prevent the medium from leaking along the gap between the sealing surface.
  The sealing pair of the globe valve is composed of the disc sealing surface and the seat sealing surface,and the valve stem drives the valve disc to move vertically along the center line of the seat.The opening height of the stop valve is small in the process of opening and closing,and it is easy to adjust the flow rate,and it is convenient to manufacture and maintain,and the pressure is wide.

1.The basic structure of the globe valve
  The valve disc,valve stem and operating device are composed.When the operating device rotates or lifts,the disc is removes fro, the seat or closed,thereby achieving fluid control.
2.The working principle of the globe valve
  Stop valve by rotating or lifting the valve disc to cut off or smooth the fluid,so as to achieve the control of convection liquid.A sealing point is formed between the disc and the seat so that fluid cannot pass through. The operating device can control the valve opening as required to regulate the flow rate.
3.Application of globe valve
  Globe valves are widely used in various industrial pipelines,buildings and urban water supply systems.It can be used to control water, oil, gas and other fluid media, very important. Because it can prevent pipeline gate leakage, control pipeline flow and adjust pipeline pressure.

4. Classification of stop valves
  According to the valve design, the globe valve can be divided into ball valve, gate valve, swing globe valve, butterfly valve, plunger valve and other types. When used, it should be selected and used according to needs.
5. Maintenance of the globe valve
  In the long-term use of the globe valve, failure and wear may occur, so routine maintenance and maintenance are required. In the maintenance, should be timely replacement of severely worn parts, and lubrication maintenance.

FAQ

How to guarantee your quality? When we install, if there is some quality problems, how to solve it?
We have QC department, quality inspector will check every step when processing and make reports to clients for checking. If any quality problems, we will check and reply you within 24 hours to solve it. Please contact us for any quality problems.

What's the temperature and pressure for valves?
For metal seat, temperature range from -196ºC to 425ºC. For soft seat ball valve, temperature range from -196ºC to 200ºC. Pressure range from PN6 to PN420(150LB~2500LB).

What's the materials of valves?
Stainless Steel, Forged Stainless Steel, Alloy Steel, Duplex Steel, Titanium Alloy, Nickel-aluminum, Bronze Alloy, etc. Details materials requirements could consult us at any time.

How about delivery time?
Our factory is near to Ningbo & Shanghai seaport, generally speaking, export to Asia takes about 7-10 days, export to Europe, Middle East, Africa, North America, South America, etc. takes about 30-35 days by sea.

What's the medium for your valves?
Mostly are used in water, gas and oil. When inquiry, it is better to offer your medium, we could suggest materials and valves type for clients.

Can ball valves regulate medium?
No, ball valves only can not use for regulating, it is a kind of isolating valve.

What are the quarter turn valves?
Ball valve, Butterfly Valve, and Plug valve are rotary motion control valves. They just need a quarter turn to come into action.

What's the direction of valves?
Ball Valve and gate valve are bi-directional valves, globe valve, check valve and y strainer have arrow on valve body to indicate direction.

What's the difference between rising stem and non-rising stem of gate valve?
The rising stem gate valve can be seen from the appearance whether the valve is closed or open. The lead screw can be seen while the non-rising stem gate valve can not. Non-rising stem gate valve handwheel will go and up when rotate handwheel, rising stem gate valve will not. And The rising stem gate valve requires a larger installation space because of the stem; the height of the Non-rising stem gate valve is small, and it will not take up too much space during installation.

What's the difference of gate valve and globe valve?
Gate valve is bi-directional valve, globe valve in single way valve and has fixed direction when install. And globe valve has better sealing than gate valve, when globe valve close, fluid medium add pressure on disc to keep better sealing. Gate Valve wedge is parallel with flange, when close, both side fluid medium add pressure on wedge.


Check Valve Introduce
Check Valve is unidirectional valve, also called one way valve, non-return valve. Because medium flow decide its direction. It has swing type, lift type(piston and ball), vertical type, butterfly type. Wafer type check valve has three types, spring return type, single disc type and double disc type. Anyway, could choose valve type according to medium, pressure and temperature. Masoneilan Valve will give you the best suggestions.

12. What's the type of butterfly Valve?
Generally speaking, for connection ends, butterfly valve has lug type, wafer type, double flange type; for design structure, butterfly valve has concentric type, double eccentric type, triple eccentric type.
