Steam Proportional Valve Control Valve of Hydraulic Fcu Control Valve Dn250 Proportional Flow Valve

VF45 Mixed valve series High closing force flange type two way regulating valve

1. Precision casting (resin sand) nodular cast iron GGG-50
2. The valve body adopts the pressure balance type, which guarantees the high clearance ability under the low pressure, and the switching free ability under the high pressure difference 
3. Maximum allowable differential pressure is 1000kpa
4. The stem seal uses special sealing process
5. The full metal joint seat increases the value of the life of the valve
6. The product meets GB/T17213-2015 flange connection standard
7. the body uses iron coated sand casting process compared with the traditional technology, there is no swelling phenomenon, body wall thickness, no pores, trachoma material of high density, more exquisite appearance The valve body and stainless steel valve port in the casting process once molding, the valve port will not have deformation phenomenon, long time high temperature use will not exist outside the valve leakage phenomenon, to ensure that the valve port factory pressure test 0 leakage. The sealing ring is made of PTFE+ carbon fiber material, which has better wear resistance The paint paint line and drying equipment make the paint adhesion stronger, the anti-corrosion effect is better, the valve body gloss has been significantly improved.
