Features and Benefits 5Gas Valve

Parker's BP Series auxiliary gas bottles share their constructionwith AP Series accumulators, and many of the design features highlighted on page 19 apply also to these gas bottles.Auxiliary gas bottles may be used singly to supplement/replacethe gas storage capacity of the accumulator, or they may be manifolded together to provide a larger reservoir of gas pressure, if required. Where gas bottles are connected by a manifold, only one bottle need be fitted with a gas valve for charging purposes. To avoid the risk of injury or damage, a gas bottle must be discharged before disassembling. For added safety, the industrial gas valves fitted by Parker vent progressively as they are unscrewed. A robust, mechanically opened/closed poppet-type gas valve rated at 350 bar is fitted as standard to all BP Series auxiliary gas bottles.

6Gas Valve Industrial protector

To prevent accidental – and potentially hazardous – damage to the gas valve, 180mm and 250mm bore BP Series gas bottles are fitted with a steel gas valve protector to reduce the risk to the valve from external impact. The gas valve on 360mm bore models is recessed within the shell to reduce the risk of damage.

1, 2 & 3Shell and Caps

Compact, rugged steel shell and end caps will survive even the toughest industrial environment, to provide reliable service year after year. 180mm and 250mm bore gas bottles feature threaded caps to minimize downtime and simplify maintenance, permitting quick and easy replacement of O-ring seals in the unlikely event of replacement being required. 360mm bore units (illustrated) use a screwed ring (3) to retain the gas caps, reducing the mass of parts handled during maintenance and providing additional protection for the gas valve.

7Ports

To provide the required gas transfer rate and simplify system design, a wide range of port types and sizes is available. BSPP ports are fitted as standard; metric flanged ports to ISO 6162 and ISO 6164 are available as an option. Note: to avoid the risk of damage or injury, an accumulatormust always be discharged before disassembly.

4Safety Bleed Grooves

A bleed groove in the gas cap progressively releases unrelieved gas pressure in the accumulator as the gas cap is unscrewed.
