Gate Valves and Knife Gate Valves: Isn't One Just Sharper?

Oct 16, 2014 · The seats on the knife gate valve come in everything from metal to resilient types. Two of the knife gate's biggest advantages knife are weight and expense. A 16 knife gate valve will typically weigh less than 300# while an ANSI gate valve will be in excess of 1200#. The cost of the valve is similar to the weight difference as well.Knife Gate Valve - Wafer Knife Gate Valve, Flange Knife knife gate valves with metal or soft and resilient seatsKnife gate valve are named for its sharp, knife-like disc, which could be used for cutting medium. The groove around the seat permits the gate to push particles aside and prevents clogging. When the valve is open, the flow cleans the groove. Seat is outside the flow area resulting in higher flow coefficient with minimum pressure drop.Knife Gate Valves Metal Seated - Welcome to FNW ValveIt is designed for the pulp and paper, chemical, mining, power, petroleum, and food process industries, as well as municipal water and waste treatment plants.

What is a gate valve and where is it used? - AVK International

The parallel gate valves use a flat gate between two parallel seats, and a popular type is the knife gate valve designed with a sharp edge on the bottom of the gate. The wedge-shaped gate valves use two inclined seats and a slightly mismatched inclined gate.What is a gate valve and where is it used? - AVK InternationalGate valves can be divided into two main types: Parallel and wedge-shaped. The parallel gate valves use a flat gate between two parallel seats, and a popular type is the knife gate valve designed with a sharp edge on the bottom of the gate. The wedge-shaped gate valves use two inclined seats and a slightly mismatched inclined gate.When To Use Metal Seat Valves Vs. Soft Seat Ball ValvesHowever, soft seats are not recommended for process fluids that are dirty, or abrasive. Soft seats can break down in these conditions, causing the valve to leak. Metal Seated Ball Valves. The primary advantage of metal seated valves over soft seated valves is their ability to withstand high temperatures and severe service conditions.
