[0002] Valves are control components in fluid delivery systems with functions such as shutoff, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. A knife-type gate valve is a valve in which the gate and valve seat are always in close contact and sealed.
