MONOVAR® : the energy dissipating valve
![Energy Dissipating Valve](https://static.wixstatic.com/media/381818_85096a7f06e344e2b8d95df36cc1e667~mv2.png/v1/fill/w_183,h_379,al_c,q_85,usm_0.66_1.00_0.01,enc_avif,quality_auto/Monovar.png)
Features
• Extremely simple design (patented)
• Excellent cavitation characteristics
• Very accurate flow or pressure control
• Manual or automatic control
• Suitable for flow measurement
• Small sizes are available
• Minimum flow disturbance
• The flow is divided equally over a larger
number of jets. This ensures an accurate
and stable performance
• These unique features, together with the
wide range of construction materials make
MONOVAR® valves an automatic choice in
all severe industrial and water-supply
situations requiring fluid flow control or of
some associated characteristic, e.g.
pressure, temperature and level
• The design suppresses vibration, cavitation,
pressure fluctuations and excess noise
• Suitable for high velocity applications
• Suitable for high pressure drop applications
Application of MONOVAR®:
- Water supply systems (reliability, pressure,
cavitation),
- Industrial flow, cooling and mixing systems
(cavitation, sensitivity, pressure, reliability),
- Head works of water treatment plant
(reduced civil works, cavitation, reliability),
- Laboratory test-rigs (sensitivity, absence of
disturbances),
- Turbine bypass (dams),
- End of line, free discharge,
- Replace variable speed pumps with
constant flow or constant pressure pumps
in combination with MONOVAR®,
- Seawater applications on request.

CLASAR : the high dynamic response check valve.
Features
• Closing time (dynamic response) is a
fraction of a second
• Avoids pressure surges in the pipeline or
minimizes them
• Suitable for high pressure applications
(PN50 - 725 psi)
• No risk of axial disc jamming as the
CLASAR® does not have an axial shaft
• Short face to face, enabling easy
installation
• Perfect disc sealing
• Excellent erosion resistance of the axial
disc
• Corrosion free axial disc material
• No maintenance required
• Suitable for a wide range of applications
due to the available materials
Benefits
• In case of sudden pump emergency stops,
CLASAR® check valve reduces pressure
surges in the pipe line
• Silent and non-slam check valve
• Easy installation
• Suitable for vertical, horizontal and
diagonal mounting
• Quick flow recovery Applications
• Water pumping stations:
- potable water
- irrigation
- water process
- seawater
• Chemical industries
• HVAC application
Technical data
• Size range: DN80 - DN1800 (3” - 72”)
• Maximum working pressure:
- DN80 - DN500: 50 bar (725 psi) at ambient
temperature
- DN600 - DN800: 25 bar (362 psi) at
ambient temperature
- DN900 - DN1000: 20 bar (290 psi) at
ambient temperature
- DN1200 - DN1800: 16 bar (232 psi) at
ambient temperature
• Temperature range: -10°C to +130°C
(+50°F to +266°F)
• Flange accommodation:
