Advantages of Resilient Wedge Design The wedge gate employs a two-piece resilient structure that automatically compensates for valve body deformation caused by temperature fluctuations, ensuring reliable sealing under low/high-temperature conditions.
Non-Rising Stem Characteristics The stem nut is connected to the gate, allowing the stem to rotate without lifting during operation. This design minimizes installation height, making it ideal for space-constrained piping systems.
Rubber Sealing Performance X-type rubber seals provide zero-leakage performance (compliant with ISO 5208 Class A), but note that the medium must not contain sharp particles.
⚠️ Limitations
Not suitable for corrosive media (stainless steel valve body required for such applications)
Metal hard-seal gate valves must replace rubber-sealed valves when medium temperature exceeds 120℃
Install filters for media containing solid particles
