Valve with inflatable seal
Description

The Inflatek® valve provides long life and reliability when handling hot and abrasive materials.  The unique inflatable seal traps abrasive particles on closing preventing their movement under the effect of the pressure differential. This action ensures wear resistance from particles, operating reliability and valve performance.

It ensures reliable leak proof seal that prevents ultra fine powders as well as abrasive granules from seeping into vessels. A valve that requires low maintenance and simple inspection makes it easy on the whole process it is involved in. It is used with pressure vessels when dealing with dense phase pneumatic conveying.

Suitable where the work environment must remain clear of dust. This valve provides total containment via an inflatable seal. Able to withstand temperatures as high as 350°C, it is available in a wide range of metals to better suit your product characteristics.

90° rotation

The spherical component rotates 90°to pass through a static or moving column of abrasive ash to the closed position where an inflatable seal is pressurised to entrap particles and prevent their movement.

Inflatable seal is available in all kinds of polymers

Capable of maintaining a seal in 100% vacuum or even when there is a vacuum on one side of the valve and positive pressure on the other.

Features

Technical specification

Inflatable seal is available in all kinds of polymers to suit an array of materials ranging from abrasive dusts to food products.
The design of the seal self-compensates the valve while in use from friction.
Whether the material is flowing into a void or sits static in a column, the valve is intended to cut through and provide an air tight seal.
Valve has one moving part with a lubricated for life bearing and designed for low-maintenance.  Replacement can be performed within an hour.
Tungsten Carbide or Teflon shell are offered for those whose materials are abrasive or cohesive.
Capable of maintaining a seal in 100% vacuum or even when there is a vacuum on one side of the valve and positive pressure on the other.

The operating sequence of the Inflatek® valve is very simple and effective:
The spherical component rotates 90 to pass through a static or moving column of abrasive ash to the closed position where an inflatable seal is pressurised to entrap particles and prevent their movement. The inflatable seal reliably achieves a pressure differential of 7barg (100psi) at a high temperature.
The standard size range is 2” to 16” and 670ºF with inline configuration for pipeline service or bulkhead configuration for pressure vessel inlet. Special Inflatek® Valves are available to 30” and 43 barg (623.5psi) with a range of materials of construction.
