Imported Self-Regulating Valves, Self-Regulating Pressure Reducing Valves, Principle and Structure of Self-Regulating Valves
Import Self-Regulating Pressure Control Valve Product Overview
Germany VordWODEThe self-contained pressure regulating valve for import does not require external energy. It uses the energy of the medium being adjusted as the power source to introduce the actuator and control the position of the valve core, thereby altering the pressure difference and flow rate at both ends, ensuring stable pressure before (or after) the valve. The self-contained pressure regulating valve boasts advantages such as sensitive operation, good sealing, and minimal fluctuation in the set pressure point. It is widely used in automatic control for stabilizing pressure or relieving pressure in gases, liquids, and other mediums.
The WOODE Valve self-contained pressure regulating valve series includes three types of structures: single seat, sleeve, and double seat; the actuator comes in two types: diaphragm and piston; and the functional types include pressure reducing valves for post-pressure regulation.(BType)Pressure Regulation Before Pressure Relief ValveKType). The nominal pressure ratings of the product arePN16、40、64Valve body diameter rangeDN15～300Leakage rate gradeIIGradeIVGrade andVIGrade 3; quick opening flow characteristics; pressure segment regulation from15～2500KpaAvailable for combination as per customer's operational requirements.
Section 2: Imported Self-Regulating Pressure Control Valve Product Features
（1Self-contained pressure regulating valves require no external energy and can operate in environments without electricity or gas, offering convenience and energy savings.
（2Fine pressure segmentation with overlapping ranges and high adjustment accuracy.
（3Pressure setpoints can be continuously adjusted during operation.
（4Pressure regulation after the valve; the ratio of the pressure before the valve to the pressure after the valve can be10：1～10：8。
（5Rubber diaphragm detection with high actuator accuracy and sensitive operation.
（6Utilizing a pressure balance mechanism, the regulating valve responds sensitively and controls precisely.
