Stainless Steel Ball Valves

Stainless Steel Ball Valves were included in our product range to complement our Camlock Coupler offering. A ball valve is designed primarily for On/Off function, to be used wherever flow needs to be controlled. They are generally the most competitively priced of any valve configuration. In addition to quick, quarter turn on-off operation, these valves are compact, require no lubrication and give tight sealing with low torque. A full-bore (full port) valve will provide virtually no obstruction to flow and as result pressure drop is negligible.

 

We service clients across industries including the petrochemical and chemical, food and beverage and Water, Oil and Gas (WOG) industries. Our Stainless Ball Valves are manufactured in High Grade Stainless Steel 316. Also referred to as an SS Ball Valve or a Ball Valve Stainless Steel. Ball Valve Suppliers please call for trade pricing.

How to Size a threaded Ball Valve:

The size of the pipe the valve threads onto will determine the size of the valve. A 1” threaded pipe will take a 1” Ball Valve.

General Ball Valve use?

SS Ball valves are used wherever flow needs to be shut-off. This allows pipes or hoses to be connected and disconnected without spillage.

Ball Valve operation and their benefits?

A hollowed out pivoting ball is turned with a handle. It's a quick 90° turn. When the handle is running parallel to the valve, flow is open and when the handle is positioned at right angles to the pipe, flow is closed. You don’t have to make too many turns to get the water to flow or to shut-off. Great in a panic situation. There’s also no guessing. You know when it’s on and you know when it’s off. The way the valve is constructed, you have a heavy body with the stop catch cast into the body. When the valve goes up against it, you’re going to feel that positive stop. You know you can’t turn it more. The same goes for when one opens it. The seal is located in the body of the ball valve and presses up against the ball. As you turn the valve open or closed the valve makes contract with the seals. They maintain the water proofing ability of the valve through-out its life.

What is Full Port?

For Full Port the valve hole actually matches the pipe it’s connected to. The pipe is ¾” and the valve is ¾”. When not full port, the ball valve is actually a little bit smaller than the pipe diameter and will limit the water flow through the pipe.

Why are PTFE seals used in the ball valve?

The main advantages of PTFE seals are high chemical resistance, wide operating temperature and pressure ranges and they can withstand dry running. The best-known brand name of the PTFE-based formulas is Teflon. An inferior seal will result in a leaking valve when ‘running’ and ‘closed’.

One Piece Ball Valve vs Two Piece Ball Valve vs Three Piece Ball Valve

In the single piece design valve, the body is cast/forged as one piece. The insertion of the ball will be through the end of the body. This design restricts the valve to a reduced bore. In the 2 piece design, the body is constructed in two pieces and the ball is held in position by body stud. The two piece body allows the valve to be manufactured with a larger ball making this a full bore valve. There can be full port or regular port design possibilities with this construction. In the case of three piece construction, the body has two end pieces and one centre piece. The center part of the valve containing the ball, stem & seats to be easily removed from the pipeline. This construction permits in line servicing and cleaning without disturbing the existing pipe work. This ball valve can be taken apart the quickly and easily. A well designed valve will not leak, a poorly designed product will leak regardless of the configuration.
