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
