CAST IRON AND BRASS GATE VALVES
Gate valve (gate valve) is a valve in which the plug is a gate valve. It can be straight section (guillotine) or inclined section (wedge) depending on whether it is used at high or low flow rates, respectively. It is always used as a shut-off valve; however, it is not suitable as a control valve. In fact, the plug causes strong turbulence in the flow and consequently rapid erosion of the sealing parts, as well as noisy and undesirable vibrations when closing.
