Description

The 3-Piece Stainless Steel Ball Valve is a robust and serviceable isolation valve designed for reliable shut-off in industrial, commercial, and general process applications. Manufactured from ASTM A351 CF8M stainless steel, it offers excellent corrosion resistance and long-lasting performance across a wide range of compatible media.

The 3-piece body design allows easier maintenance and servicing compared with one-piece and two-piece valve designs, making it well suited for applications where access, inspection, or future maintenance may be required.

Featuring a full bore design, this valve provides high flow capacity with minimal pressure drop. The PTFE seats, blow-out proof stem, and investment cast body provide dependable sealing performance and durable operation.

The lockable lever handle allows the valve to be secured in position, making it suitable for applications where valve operation needs to be controlled, restricted, or clearly isolated.

What is a 3-piece ball valve and why is it used?

A 3-piece ball valve consists of three main sections — a central body plus two end pieces — bolted together. This design lets you remove the middle section for inspection, maintenance or seat replacement without removing the entire valve from the pipeline, which can save time and reduce downtime.

What does “full bore” mean and why is it important?

A full bore (or full port) ball valve has an internal opening that is the same diameter as the pipe size. This means fluid can flow through the valve with minimal pressure drop or flow restriction, which is useful in systems needing high flow rates.

What is API 598 testing and why should a ball valve be tested to it?

API 598 is an internationally recognized valve inspection and testing standard that verifies a valve’s shell strength and sealing performance before it leaves the factory. Valves tested to API 598 must meet defined pressure and leakage criteria, helping ensure they perform reliably in service.

What are the advantages of stainless steel (316/CF8M) and PTFE seats?

Stainless steel (ASTM A351 CF8M) offers excellent corrosion resistance and strength, making the valve suitable for diverse environments. PTFE seats provide a tight seal with chemical resistance and low friction, helping the valve maintain leak-free operation over time.

What is a lockable lever and how does it help?

A lockable lever lets you fix the handle in either the “open” or “closed” position using a padlock or locking device. This is a useful safety feature that prevents accidental operation when maintaining or isolating a system.
