GTVS/GTRS
2- and 3-way flanged valve
• Size DN32–150
• Kvs value 16–310
• Differential pressure 0.12–1.3 MPa
Control valves intended for use in heating and ventilation
systems, suitable for cold and hot water, glycol-mixed
water or steam.
• Pressure rating PN16
• Media temperature -5...+120°C
Function
GTVS:
The valve is open when the stem is at its lower position
and closed when the stem is at its highest position.
GTRS:
As the stem is at its lower position, flow-through between
ports A and AB is entirely open (and closed between
ports B and AB). As the stem is at its highest position,
flow-through between ports B and AB is entirely open
(and closed between ports A and AB).
Actuators
The valves are intended to be used together with
actuators of the type RVA... The OVA-F1 adapter kit is
factory mounted on models with DN32-40 and OVA-F2
is mounted on models with DN50-150.
Installation
The valves are to be mounted according to the flow
direction arrows on the valve.
The 2-way valve is to be mounted with port A as intake
and port AB as return (flow direction A in, AB out) to
ensure tight closure and prevent noise when closing.
The 3-way valve is of mixing type and should be mounted
at the mixing point.
Make sure to mount the 3-way valve so that correct flow
directions are obtained.
Material
Body in cast iron and stem in stainless steel. Plug and seat
in gunmetal. Self-adjusting PTFE packing box and O-rings
in Viton.
Control of refrigerants
The valves can be used with different refrigerants. In this
case, a special type of packing box must be mounted.
