Slide Gate Valve Vs Knife Gate Valve

Our staff has many years of combined experience in building knife gate valves in particular.

Slide gate valve vs knife gate valve.

We handle every facet of the fabrication process from engineering to. Knife gate valves were designed with a sharp edge to cut through the pulp and seal. Knife gates are to cut through thick liquids and gases. A knife gate valve is just what it implies.

Pratt knife gate and slide gate valves have been produced since 1995. Knife gate valves are used to cut through extremely thick fluids and dry bulk solids. The gate valve is only available with metal seats. Gate valves use a movable door or gate to open and close the valve.

Stringy pulp would impinge between the wedge and seat of a normal gate valve and prevent flow shut off. The knife gate valve was designed with a sharp edge to cut through the pulp and seal. We specialize in custom knife gate valves from 2 to 96 and above utilizing carbon steel to stainless steels and other weldable alloys. This gate is lowered or raised using a mechanically assisted operator which is normally a threaded screw.

Avk knife gate valves are available with lever non rising stem and. What makes it different from other flow control valves such as butterfly valves and bull nose knife gates. Whereas a slide gate valve is a component utilizing a slide plate in order to better manipulate or control the flow of dry bulk material. Knife gate valves were originally designed for the pulp and paper industry.

The fundamental difference is the quantum series orifice slide gate is designed specifically to handle dry material like powders pellets and granules. Knife gate valve with rising stem and handwheel for wastewater treatment 0 c to 80 c avk lug wafer knife gate valves are bi directional with full and plane bore. The gate unit of this type of valve is thin compared with other gate valve types and is guided in. Another significant difference between an ansi gate valve and a knife gate valve is in the packing gland area.

A gate valve will have a v ring packing set that seals the shaft attached to the gate while a knife gate valve has a packing gland that seals around the gate. Knife gate valves perform exactly as the name implies. Knife gate valves were originally designed for use in. The purpose of a knife gate valve is to cut through solid or semi solid flows of heavy liquids utilising a blade unlike a slide gate valve which is a valve that uses a slide plate in order to control the flow of dry bulk material.

Stringy pulp would impinge between the wedge and seat of a normal gate valve and prevent flow shut off. Since gate valves can either be in the fully open or fully closed state the resistance of the fluid flow when the valve is fully opened is smaller. The orifice slide gate valve. These types of valve were originally designed for the pulp and paper industry.

The protected sealings and high quality materials bring about a great performance and a long service life.
