Forged Gate Valve


Description of Forged Gate Valve:

ZECO is a manufacturing plant for forging gate valves. Forged gate valves are suitable for various industrial conditions, and can be used for the installation of ground pipelines and underground pipelines. Because forged valves have better corrosion resistance than cast ones, they can avoid the high cost of frequent replacement caused by corrosion. According to the connection mode, forged gate valve can be divided into four types: threaded connection, socket welding connection, butt welding connection, and flange connection. The threaded connection is one of them, which can be mainly used for internal thread connection or external thread connection and pipeline thread connection. Threaded connection is usually used for middle and low-pressure pipeline; Socket welded connections are suitable for high-pressure pipelines, usually found in small diameter forged gate valves less than 2 inch; Butt welding is also suitable for high-pressure pipelines, but it usually occurs in large diameter forged gate valves of more than 2 inch; Flange connection can be divided into integral flange and welding flange two kinds, according to the specific working conditions of users to choose; Forging gate valve is mainly used for cutting off, so it can be applied to the pipeline with bidirectional flow of medium.


Features of Forged Gate Valve:

1. ZECO forged gate valve adopts the reverse sealing design. In the long-term use, if the packing needs to be replaced, as long as the valve is fully open, the packing can be replaced online without leakage of the valve;

2. The T-head stem design of ZECO forged gate valve provides positive disc to stem connection and ensures effective seating operation;

3. The fully guided solid wedge of ZECO forged gate valve reduces wear on seating surfaces;

4. The stud and bolt arrangement of ZECO forged gate valve facilitates packing maintenance.
