Ball Valves By Construction

Trunnion ball valves are quarter-turn valves used to stop or start the flow of a media in a pipe.

SQK Single Piece Ball valve as the name suggests is made out of one body piece unlike the 2 and 3 piece. This means the valve cannot be taken apart for cleaning. The advantage is that the valve will be low cost and robust. As a result of the valve body being one piece is that a smaller ball has to be used leading to a reduced port, more commonly called a reduced bore. This means that flow is reduced through the valve, since the ball bore is one size smaller than the pipe size.

SQK three piece ball valve is preferred wherever regular cleaning is required. The valve body is composed of 3 separate pieces held together by bolts, which can be easily removed for cleaning and servicing. A unique advantage of the 3 piece valve design is that the ball valve ends can remain threaded into the pipe, while the center section containing the ball can be removed. These 3 piece ball valves have been specifically designed to be easily disassembled, cleaned, and reassembled. 3 piece stainless Steel ball valves also called 3 SS ball valves, are widely used for a variety of sanitary applications that are required for pharmaceutical and food/beverage industries.

SQK two piece stainless steel ball valve is probably the most widely used ball valve. The 2 piece ball valve will open or shut off flow on most liquids and gases quickly and easily and is suitable for just about any application where a simple on/off action is needed. Flow rate can also be controlled by partially opening or closing the valve to various degrees. Also referred to as a two-way ball valve, since it allows flow in any direction straight through from inlet to outlet. Being threaded ball valves they are quick to install and easy to use, requiring no tooling for installation. The two piece ball valve is the best priced full port ball valve (full bore), allowing the inside diameter of the pipe to remain constant and unrestricted. This means that the 2 piece SS ball valve has no pressure drop and keeps the flow rate high.

SQK Gear operated ball valves are one of the most reliable methods of directing and containing fluid flow in several different industries. They come with low flow resistance so that you can have amazing control over your fluids while still moving them along as quickly as needed. Ames Gear Operated, Lead Free Slow Close Ball Valves are UL/FM rated for use in fire suppression systems and approved for indoor and outdoor use. They have integrated supervisory switches with a reversible switch box, for simplified electrical wiring access. These gear operated ball valves are available in threaded or grooved ends, with chrome-plated brass ball, brass stem and PTFE seats for low torque and positive shut off.

SQK side-entry ball valve is a type of valve that has a stem that connects the ball on the side. Aside from this, the ball is also connected to the stem through a quarter-turn thread. This type of ball valve is cheaper than the top-end valve. Unlike the top entry ball valve, you have to remove the valve from the pipe in order to repair it as the handle is on the side.
