Pilot Operated

Temperature Control Valve with SG Iron Body

Description

The 37D is a pilot operated temperature control valve suitable

for use on steam applications and comes complete with 2 m of

capillary tube as standard (other lengths are available on request

- see Optional extras).

By virtue of it's pilot operation, it has a comparatively small control

band.

The sensor of the control system will need to be mounted by either a

union kit, pocket or wall mounting bracket - see 'Optional extras'.
