Cast Iron Valve
There are many materials in the valve
, but in the water system valves
, cast iron valves
and ductile iron valves
are used more widely because the pressure required on the water system is not particularly high and the relatively cheap cast iron material can cope. Cast iron butterfly valves
are common because of its high-cost performance, coupled with the unique EPDM seat made by Zhengfeng to stabilize their performance in the water supply and drainage system.
Another common cast iron gate valves, especially in bidding to 4 inch cast iron gate valves to compare prices or appearance, are abundant in addition to will focus on the study of its material, at the same time to the stem, the material of nut is investigated, because for phase often soaked in water valve, anti-corrosion and durable is the most critical factor. Such as cast iron pressure reducing valve, cast iron float valves or cast iron foot valve, our company is professional manufacturer of China and Australia, we will study the biggest pressure reducing valve range and the decompression of voice for maximum design to reduce the noise, the cast iron foot valve we adopt the most authentic material SS304 in place to ensure that in the process of underwater soak filter is not damaged by corrosion. Zhengfeng has been focusing on cast iron valves of the water system for more than 20 years and has carefully developed cast iron valves suitable for water supply and drainage, fire control system and HVAC system. The laboratory owned by the company will carry out chemical analysis and physical performance analysis on each batch of cast iron materials to ensure the safety of raw materials.
