feature
1. Angle type zero leakage compact design: adopting a 90 ° right angle flow channel and metal corrugated pipe sealing integrated design, while realizing the right angle conversion of pipeline direction, the valve stem is completely isolated from the medium through multi-layer corrugated pipes, fundamentally eliminating the leakage path at the valve stem, especially suitable for space limited pipe galleries and compact equipment layouts.
2. Adapt to high pressure differentials and harsh thermal conditions: The pressure bearing parts of the valve are designed strictly in accordance with DIN/EN standards, and the key sealing components are made of high-temperature resistant alloys certified by European standards. The corrugated pipe has undergone multiple wave hydraulic forming and solution treatment, and has excellent resistance to pressure pulsation and thermal cycle fatigue. It can maintain long-term sealing in high temperature, high pressure, frequent start stop, and corrosive media.
3. Dual safety and emergency protection: On the basis of the main seal of the corrugated pipe, a packing box that meets DIN standards is retained as the secondary sealing system. When the corrugated pipe reaches its service life or is accidentally damaged, the stuffing box can immediately play an emergency sealing role, providing a safe buffer for system maintenance and preventing sudden leakage accidents.
4. Flow resistance optimization and stable adjustment: The angular flow channel design significantly reduces turbulence and pressure loss when the medium flow direction changes. The valve disc adopts a low torque guiding structure, combined with the frictionless motion characteristics of the bellows, to achieve smooth valve opening and closing and precise opening, especially suitable for working conditions that require frequent adjustment or high pressure difference cut-off.
5. European standard integration and easy maintenance: strictly manufactured according to DIN/EN standards, using PN series flanges or butt welded end connections, fully compatible with mainstream European pipeline systems. The modular design of corrugated pipes supports online maintenance, allowing for the replacement of sealing components without the need to remove the valve body, significantly reducing downtime and maintenance costs.
6. High purity applicability and intelligent diagnosis: The all metal sealing system eliminates non-metallic material precipitation and pollution, meeting the requirements of EU GMP, FDA and other clean standards. It can integrate corrugated pipe life monitoring sensors and intelligent actuators to provide real-time feedback on sealing status and performance data, achieving predictive maintenance and digital management.
