| Product： |
Low Temperature Gate Valve
|
| Item No.： |
DZ40Y |
|
| Calibre： |
DN20-300 |
| Nominal Pressure： |
1.6-10MPa |
| Description: The opening and closing part of the low temperature gate valve is the gate, the direction of movement of the gate is perpendicular to the direction of fluid, the gate valve can only be fully open and closed, can not be adjusted and throttled. The gate has two sealing surfaces, the most commonly used mode gate valve two sealing surfaces form wedges, wedge angle varies with valve parameters, usually 50, when the media temperature is not high at 2'52'. The gate of the wedge gate valve can be made into a whole, called a rigid gate, or a gate that can produce trace deformation to improve its processability and make up for the deviation caused by the angle of the sealing surface in the process, which is called an elastic gate. |
|
|
Specification: Full diameter, clear rod with bracket, mid-flange bolt connection, guided elastic gate, U.S. standard structure improvement, lengthened insulation neck, umbrella gear operation optional, standard flange connection.
