Forged Steel Gate has advantages and disadvantages

Forged steel gate valve most of the Dalian type necking design flow to be smaller compared with the same caliber of cast steel gate valve , the pressure and higher temperature range than cast steel valve sealing performance than cast steel The gate valve is better, live longer, unrestricted flow direction of medium like any other gate valve. : Gate with high-quality rubber overall outsourcing glue, Europe's leading rubber vulcanized to the gate to ensure accurate geometry, then solid rubber and ductile gate after the curing, easy to fall off and good elastic memory . The body uses the precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve.

The forged steel gate valve has the following advantages:

A small fluid resistance, the sealing surface is distressed by the media to brush and erosion.
2, open and close more effort.
3, the medium flows unrestricted, non-spoiler, not reduce the pressure.
4, a simple form, the short length of the structure, good manufacturing processes for a wide range.

The merits and demerits of the forged steel gate valve as follows:

1, between the sealing surface could easily cause erosion and abrasion, and maintenance more difficult.
2, Dimensions, open space, opening and closing a long time.
3, the structure is more complex.
