High Performance Non Slam Check Valve

High-performance non-impact check valve is an automatic valve that eliminates the impact force and water hammer effect when the valve disc is closed through special structural design (such as spring damping, inclined disc valve disc), ensuring one-way flow of fluid without noise and mechanical damage. Its core goal is to prevent the backflow of the medium while optimizing the stability and safety of the pipeline system.

‌Structural composition‌

Valve body‌:
The material is ductile iron, carbon steel or stainless steel, which is corrosion-resistant and suitable for high-pressure environments.

Connection forms include flange, thread or wafer type to meet different pipeline installation requirements.

Valve disc and drive components‌:

Inclined disc valve disc‌: Reduce the impact force when closing (compared with traditional swing valve disc) through the tilt angle design to achieve smooth opening and closing.

‌Spring damping device‌: Built-in high-strength spring (such as Inconel X750) or hydraulic buffer to absorb the kinetic energy of valve disc closing and avoid water hammer effect.
Sealing system‌:
The sealing surface is made of ‌alloy cladding‌ or ‌PTFE coating‌, with a hardness of ‌HRC55~65‌, erosion resistance and a leakage rate of ≤0.01%‌.

‌Nominal diameter (DN): DN50~DN1200, covering the needs of small and medium-sized to large-diameter pipelines. ‌

Pressure level (PN): PN16~PN420 (corresponding to Class 150~2500), suitable for high-pressure and ultra-high-pressure conditions. ‌

Temperature range: -196℃~450℃, supporting extreme media such as liquefied gas and high-temperature steam. ‌

Core advantages‌

• Eliminate the water hammer effect‌: Through the damping device or swash plate structure, the closing impact force is reduced by ‌70%~90%‌ to protect pipelines and equipment‌. ‌
• Long-life design‌: The wear-resistant sealing surface can withstand ‌≥100,000 opening and closing cycles‌, reducing the maintenance frequency. ‌
• Fast response‌: The valve disc opening and closing time is ≤0.1 seconds to prevent backflow from causing system failures. ‌ ‌
• Multi-condition adaptability‌: Compatible with high pressure, low temperature, and corrosive media (such as sulfur-containing oil and gas, liquid nitrogen)‌.
