Features
◆ Good corrosion resistance: the inner cavity of the valve body, the valve core, the valve seat and the valve stem are all lined with 2.5-3mm thick polyethylene propylene F46 or polytetrafluoroethylene, which can resist acid and alkali and strong corrosion;
The sealing performance is good: the use of PTFE material bellows and packing double seal, to ensure no leakage;
Small leakage: due to the use of soft seal, so the leakage is small, and even can ensure no leakage;
The regulation of flow and high precision: due to the use of straight travel valve, straight travel valve is the biggest advantage of high regulation accuracy, flow coefficient can be achieved at least 10-2 orders of magnitude, which is other types of corrosion-resistant valve can not match.

Angle type valve is easy to forge, so often can be transformed into angle type high pressure regulating valve. The problem with high-pressure valves in use is that they have a short life, and the valves of the general structure can only be used for 1-2 months under high pressure differential conditions. The fundamental reason for the short life is that the medium is prone to flash evaporation, cavitation and erosion under the condition of large pressure difference, causing strong damage to the inner parts of the valve.

Angle-type high-pressure valve can only be used for angle-type installation of the place, if there is no such pipeline, the pressure is quite high, the choice of straight-through high-pressure valve becomes a necessity. Straight-through high-pressure valve has the characteristics of straight-through installation, the valve body adopts forging type, pressure and temperature resistance performance is good. If the high pressure differential valve, VALCAM adopts multi-stage step-down anti-cavitation measures, greatly improving the service life of the valve.

High pressure valve is one of the special valve type in the control valve. Due to the high fluid pressure, even the temperature is very high, the manufacture of the valve, the application has higher requirements. Especially in the synthetic ammonia system, urea system and other chemical applications are more extensive, if the valve structure, improper selection, will make the use of the effect is greatly reduced.
