Series 82/83 and AF82/AF83 Full Port Ball Valves

Maximum capacity, minimum restriction
and optional fire rated design.

Worcester's Flanged, Full Port Valves are designed to meet recognized industry standards in a wide variety of industries including, chemical processing, petrochemical, oil and gas production, pulp and paper and others.

Capable of handling a wide range of liquids, suspended solids and gases in these industries, these valves offer all the advantages inherent in a ball valve; quick, quarter-turn operation, visual indication of the valve position, straight uninterrupted flowpath, and compact size. Plus, the full port feature mini mizes the pressure drop across the valve - important for critical process applications, while maximizing flow capability and throughput economy - for general line services.

Designed with firesafety in mind, their rugged split body construction facilitates inspection and repair while insuring long life and durability. Like all Worcester ball valves, they offer tighter shutoff, high cycle life, low torque operation, and the ability to automate with a choice of actuation. When you consider these and other features that we have built in as standard to our 82 and 83 Series Valves, you will know why Worcester has been at the forefront of ball valve technology for over 30 years, and you will know why so many engineers specify WORCESTER - NO EQUAL.

Secondary Metal Seats Provide Firesfety - machined into the seat area of the body cavity are raised metal lips which perform several functions.

In normal service they help support the seat, to prevent them from deforming and also help shield them from abrasive media.

If the valve should be subjected to a fire, the lip acts like a dam to prevent the softening downstream seat from being forced into the port and creating a leak.

When the seat is totally sublimated in a fire, the lip acts as a secondary seat forming the metal to metal seal with the ball.
