Icon Industrial Specialties Now Offering Alta Robbins 314 Series Valves

Icon Industrial Specialties is pleased to announce that it is now offering Alta Robbins Series 314 valves on all of our sample cylinders. The Series 314 offers a unique seat design. As you will see "The Difference is in the Seat"

Robbins Aviation pioneered the concept of a large, durable, and fully contained soft seat. This rugged seat design enables our valves to be used in a wide range of applications for extended periods of time with zero leakage. A brief examination of the design differences between Alta-Robbins valves and those of our typical competitors shows why we say “The Difference Is In The Seat!” The Robbins difference begins with a large soft seat which is pressed into the cup of the bonnet assembly. The bonnet assembly is then threaded into the valve body resulting in complete containment of the seat. Metering is produced as the stem tip moves up and down through the seat orifice. Bubble tight shut-off is achieved as the flat of the stem meets with the top of the seat Very low torque is required to achieve bubble tight shut-off. Even though only low torque is needed for bubble tight shut-off, experience has shown that operators and technicians use great force when closing valves, often resorting to the use of wrenches or channel locks. Our typical competitor’s seats are relatively small in size and are installed directly to the tip of the stem. It moves up and down with the stem and is completely un-contained. Each time that the un-contained soft seat is forced into the edges of the through hole, it loses it’s shape as it “squishes out”. To ensure that it doesn’t leak, the operator continues to tighten, and tighten, until it actually cuts all the way through the seat resulting in metal to metal shutoff. Robbins valves simply do not leak, even under sever abuse. Our customers have reported that, even in the extreme instance of an operator “over-closing” a Robbins valve with a wrench to the point of actually twisting the stem off, the seat did not leak.

Icon welcomes the Alta Robbins line to our product offering and we look forward to a long and healthy relationship.
