Double block and bleed valve
Type Typ DBBV (Control Seal)
Pressure: ANSI 150 - ANSI 2500 (~PN20 - 420)
Nominal size: 1" - 48"
The double block and bleed valve guarantees 100 % tightness due to the special rotary-lift movement.
No loss of expensive media! The double block and bleed valve can be used instead of 2 gate valves so that the cavity can be completely emptied at all times.
The special opening and closing method minimises wear and ensures a long service life.
ANSI double block and bleed ball valve, floating
(JC Valves)
Pressure: 10 - 172bar
Nominal size: 1/2" - 4"
"The JC Valves “double block & bleed” (DBB) valves are designed and produced to provide a reliable alternative to multi-stage shut-off valves.
They reduce the possible leakage points, lower installation and maintenance costs.
Combining all the shut-off and drain components within a valve leads to a significant reduction in weight and piping.
The valves are either available in a flanged or bolted design."
Double eccentric , double flanged butterfly valve
(TTV)
Double eccentric butterfly valve
Type ROCO wave (ERHARD)
Pressure: '10 / 16 / 25 / 40
Nominal size: 150 - 1600
The double eccentric butterfly valve ROCO wave is designed for water applications.
The valve is characterised by high energy efficiency, a flow-optimised design, minimal pressure losses and continuous corrosion protection.
The connection between the shaft and valve disc is covered by a polygon connection.
The double eccentric butterfly valve has a modular actuator concept through the use of a handwheel, electric actuator, stem extension, weight-loaded hydraulic actuator, pneumatic actuator or chainwheel.
Double eccentric butterfly valve
Type EAK (ERHARD)
Pressure: '6 / 10 / 16 / 25 / 40
Nominal size: 700 - 3600
The double eccentric butterfly valve EAK is used in water applications with large nominal diameters.
The butterfly valve offers a modular actuator concept through the use of a handwheel, electric actuator, stem extension, weight-loaded hydraulic actuator, pneumatic actuator or chainwheel.
