BEFORE INSTALLATION

This normally-open, single-seated, straight-through,

pneumatic valve provides two-position or proportional control

of two-pipe hot water or steam systems.

The valve can be installed in any position. The direction of

flow must be in the same direction as the arrow cast on the

valve body.

Refer to Fig. 1 for dimensions to determine the space required

for proper installation. Be sure to allow enough clearance

around the actuator top for servicing after installation.

VP525A,C PNEUMATIC RADIATOR VALVE INSTALLATION Threaded Union Body Version Typical applications of straight-through and angle pattern union connected valves are shown in Fig. 4. The direction of flow must be toward the union connected end (the same direction as the arrow cast on the valve body). Use proper piping methods when installing the threaded union body to prevent distortion of the valve body (see Fig. 5).

VANNE PNEUMATIQUE POUR RADIATEUR VP525A ET C INSTALLATION Corps de vanne avec raccord union fileté Les applications typiques des vannes à corps droit ou en équerre avec raccord union sont illustrées à la Fig. 4. Le fluide doit s'écouler vers l'extrémité du raccord union, c'est-à-dire dans le sens indiqué par la flèche sur le corps de la vanne. Installer le raccord fileté selon les méthodes de tuyautage recommandées pour empêcher le gauchissement du corps de la vanne. (Voir la Fig. 5).
