• Removable manual operating handle to control valve during installation or in an event of power failure

With line sizes ranging from ½” to 2” sizes (Cv ranging from 0.4 to 250), Siemens 599 Series Ball Valves can control hot or chilled water and up to 50% glycol solution in convectors, fan coil units, unit conditioners, radiation, and reheat coils.

Features :

• Forged Brass Body
• Chrome Plated Ball
• Standard Port and Full Port Design

The Balancing Valves is designed for double regulating, control and shut off valve with built-in pressure drop measuring facility.

We have a wide range from 15mm to 300mm. It is divided in two parts, 15mm to 40mm and 50mm to 300mm as below, For 15mm to 40mm,

Application :

• The hydronic balance is a significant requirement for the efficient operation of a hydronic heating or cooling installation. In an unbalanced system under or over provision of hot water to individual radiators or circuits can occur. Apart from the correct selection of radiator valves, regulation of individual circuits is also necessary and in some cases, such as in DIN 18 380, VOB part C, required by national standards.
• The Valve is a variable orifice double-regulating balancing valve for the return with additional functions shutoff, draining and filling.
• It can be upgraded to an automatic balancing valve - even after the system has been taken into commission and under system pressure.

Features :

• Quick and easy measuring with SafeConTM measuring connections
• Dimensions DN15 to DN40 can be retrofitted with a Kombi-Diaphragm Unit
• High accuracy of pre-setting because of individual adjustment
• Robust valve body made of corrosion resistant red bronze
• Available in sizes up to DN80
• Visible pre-setting dial with concealed pre-setting wheel
• Maintenance free spindle with double O-ring sealing’s
• PTFE-seat sealing 

The PRV valve protects domestic, commercial and industrial applications against excessive water supply pressure. It reduces both water consumption and noise from water hammer, while minimising over pressure damage. The set outlet pressure can be maintained even when there are wide inlet pressure fluctuations. A drop tight seal means outlet water pressure will not increase when there is no flow. It has been awarded the Waterwise Marque.

Features :

• Outlet pressure set by turning the adjustment knob
• Set pressure directly indicated on the set point scale
• Adjustment spring not in contact with wholesome water
• Valve insert is of high quality synthetic material and can be fully exchanged
• Integral fine filter (160 microns)
• Available without fittings
• Light weight
• Reliable and proven
• Drop tight
• max. 16 bar with clear filter bowl or max. 25 bar with brass filter bowl inlet pressure
• 1.5 - 6 bar outlet pressure
• Available with pressure gauge

Options:

• 1/2" and 3/4" Female BSP connections
• 15mm and 22mm connections

Application:

The Air Vent is a reliable automatic venting device and is suitable for venting of air or gas from heating systems or heat process installations.

Features :

With the shutoff valve fitted, cleaning or re-placement of the seal and inner components can be carried out without draining the system.

Range of Application :
