Suggested Specifications:
(For architects
and Engineers)
All Thermostatic Radiator Valves (TRV) to be
self-contained (as manufactured
by American Steam Control).
Valve size to be the same as existing radiator valves. Valves exceeding 1¼"
may be reduced to 1¼" size.
Valve Selection: (select valves from table below, meeting the requirements
for your particular project application).
Project application:
Recommended TRV:
|
Steam heating system.
Problems with tampering can be expected. |
TRV 10 (Fail - close)
Replaceable Unisert 10 containing
stainless steel and Teflon disc. When thermostat is broken off or
removed valve will fail in a closed position. |
|
Hot water heating systems.
Problems with tampering can be
expected. |
TRV 20 (Fail - close)
Replaceable Unisert 20 containing
brass seat and EPDM soft disc. When thermostat is broken off or
removed, valve will fail in a closed position, allowing approximately 5% of
normal flow, for frost protection of the system. |
|
Steam or hot water heating
system.
No tampering problems are
expected.
|
TRV 30
Replaceable
Unisert 30 containing stainless steel and Teflon or Viton Disc. When the
thermostat is broken off or removed, valve will fail in an open
position.
OR:
TRV 40
Replaceable cartridge 40 with EPDM soft disc and
non-removable integral seat.
|
TRV control (thermostatic operator) selection:
On all unobstructed free standing radiators direct
sensing type L controls shall be used.
On radiators with enclosures or otherwise obstructed
radiators where direct sensing controls are not suitable remote sensing controls
shall be used. Manufacturers recommendations shall be adhered to.
Other control options:
Type W controls are smaller in size and may be
used where space problems prevent the use of the larger type L controls.
Armored capillaries are available for controls
with remote sensor.
Wall mounted controls with direct or remote
sensor are available for wall mounting or mounting on to radiator
enclosure.
Thermo - electric actuators are available where
it is desirable to utilize a room thermostat to control several radiators such
as in auditoriums or other large rooms.
ALL CONTROLS ARE INTERCHANGEABLE ON
ALL OF OUR VALVE BODIES.
