HydroControl Double regulating and commissioning valves for solar

Especially for the hydronic balancing of collector fields in solar thermal systems with closed circuits. No shutoff facility to ensure a minimum flow rate. Flow rate determination by differential pressure measurement via the integrated, fixed measuring orifice. 
Y-pattern valve with fixed measuring orifice and secured, at any time controllable, infinitely adjustable fine presetting. All functions accessible from the top. Clamping ring connection for Regusol compression fittings on both sides. Plug-in couplings for connection of a measuring device.
Valve body and bonnet made of bronze, other parts coming into contact with the medium made of dezincification resistant brass or stainless steel. Maintenance-free spindle sealing by double O-ring.
HydroControl STR are particularly characterised by high temperature resistance up to 200 °C, a minimum flow rate and a fixed measuring orifice.
