Pressure regulator

SS2 Alz-6U

Do you need a higher gas flow rate but don't want to invest in expensive solutions? The SS2 Alz-6U regulator is an alternative to powerful pressure control systems. The dual set achieves a flow rate of up to 240 m³ of gas per hour. And when one regulator needs service, the other one continues to function.

  • Weight: 25 kg

  • Minimum flow rate: 65–80 m³/h (Pv min) depending on type

  • Maximum flow rate: 140–240 m³/h (Pv max) depending on type

Double reliability

You service one controller, the other continues to operate

Up to 240 m³

High flow for demanding businesses

Three variants

Possibility of conversion according to inlet pressure

Basic overview of the SS2 Alz-6U system

Safety

  • Built-in safety valve: detects a drop in pressure after a sudden increase

  • Independent safety systems: each regulator has its own safety valve and safety lock

  • Permanent closure: in the event of a serious fault, the regulators close permanently

  • Double reliability: when one controller needs service, the other continues to operate


Materials and construction

  • All parts are made of durable materials that are not damaged by gas. The main bodies are made of gray cast iron, the other parts are made of aluminum alloy

  • Each regulator has a built-in strainer that captures debris from the pipes

  • Flange connection: quick installation without complicated pipe modifications

Easy installation and maintenance

  • The actual flow rate is 15–20% lower than the sum of both regulators (influence of fittings and transitions)

  • Three variants for different inlet pressures: AB, BD, CE cover the range 0.05–0.4 MPa

  • Refurbishable: only the damaged part can be disassembled and repaired. You don't have to buy a new product

  • Serviceability during operation: when you disconnect one controller, the other one continues to operate

  • 5-year warranty, stores and installations in 260 locations across the Czech Republic and Slovakia

Recommendation

  • Correct position: the diaphragm plane must be horizontal, the springs at the top

  • We recommend sealing materials according to DIN EN 751-1,2,3

Controller advantages

  • valve body made of gray cast iron, other castings made of aluminum alloy

  • built-in safety valve

  • built-in safety valve that permanently closes the gas supply to the regulator when the gas pressure drops or rises above a specified limit

  • dismountability and repairability

  • service provided

  • individual parts of the regulator are made of gas-resistant materials

  • The accessory includes a strainer to prevent dirt from entering the regulator

  • Flange connections allow easy assembly and disassembly of the regulator

  • possibility of conversion from type AB to BD and CE
