High Flow Model VBP Series Volume Booster Delivers System Stability

09 May 2012

Bifold announces the introduction of the model VBP series high flow Volume Booster for pneumatic and gas service.

This patent pending unique product, manufactured from 316L stainless steel, performs efficiently with a high flow in both open and close rotation of the actuator. Competitor’s booster valves have a high output flow, but a low exhaust flow. In applications where a fast response time on modulating service, in combination with a fast shutdown time (ESD), is required, the VBP also eliminates the need for an additional poppet or Quick Exhaust Valve to achieve the required closing speeds. This results in reduced material and labour costs and simplifies positioned set up and control.
When used with a valve positioner/valve actuator, the VBP is designed to produce fast opening and closing times. This range is also available as a combined filter booster.

The range functions with a working pressure range of 2 to 10 bar g, with maximum inlet pressure of 20 bar g and operates at a working temperature of -20ºC to +180ºC. The design offers a choice of two sizes with port threads of 1/4”, 3/8”, 1/2”, 3/4”, 1” and 2” NPT which allow installation flexibility for easy hookup.

The extremely compact modular design eliminates the need for additional quick exhaust valves enabling reduced costs and installation time.

Improved system design offers a simple tubed system with ONE Bifold Filter Regulator and ONE Volume Booster. The advantages = faster response times and simple to install resulting in the lowest cost solution. Conventional systems require multiple Filter Regulators and multiple Volume Boosters, the disadvantages = slower response times and requiring balancing of the Filter Regulators.

A soft seat sealing design provides tight shut off to reduce costly air consumption. A bypass needle adjustment fitted as standard across the range eliminates system hunting and providing stability. It is
manufactured from 316L stainless steel as standard.

Applications include activation of control valves used in chemical, petrochemical, oil and gas, pharmaceutical and food processing markets. This range has been designed and tested at Bifold and supplied for use with the majority of positioner/valve actuator manufacturers.
