feature
1.All stainless steel corrosion resistant structure
The valve body, bonnet, float ball and internal components are all made of 304/316 stainless steel, with excellent chemical corrosion resistance, electrochemical corrosion resistance and erosion resistance, suitable for drinking water, high-purity media, chemicals and seawater and other harsh environments.
2.Compound fast exhaust mechanism
Large bore main exhaust port and independent micro exhaust port are adopted. The main exhaust port is specially optimized for exhausting a large amount of free air at high speed, significantly shortening the system water filling or exhaust time; The micro vent continuously discharges the dissolved gases evolved during operation.
3.High-speed response and instantaneous air admission
Lightweight design of moving parts, low inertia and extremely short response time. When the system generates negative pressure, it can be instantaneously opened to suck in a large amount of air, quickly balance the pressure, and effectively prevent pipe deformation or equipment cavitation.
4.High tightness and wide temperature and pressure adaptability
The sealing pair adopts metal hard seal with precision grinding or high performance elastic seal to ensure zero leakage under frequent opening and closing and high pressure fluctuation. It can adapt to higher working pressure (PN16-PN40) and temperature range (- 20 ℃~150 ℃).
5.Sanitary design for easy maintenance
The internal and external surfaces are polished (electrolytic polishing is optional), meeting the hygiene standards of food, pharmaceutical and other industries. The structure adopts modular design, and the upper cover can be quickly opened, which is convenient for CIP and maintenance.
