NovaZone Valve

Control of volume flows for different fluids in HVAC systems

Description

and spring return for control in HVAC systems. System parts or individual units are supplied with fluid or switched off depending on the switching criterion (open/closed for 2-way valves and switching for 3-way valves). With lever for manual operation. The valve setting is visible. Stuffing box seal provided by two successive O-ring seals.
Range of applications for different fluids (water, glycol mixtures).

Advantages

  • Short actuating times (max. 20 seconds)
  • Robust design
  • With lever for manual operation
  • Low maintenance
  • Visible valve setting
  • For water, glycol/water mixtures

Functions

The valve body is moved from its initial to its final position by means of a 1-pin control contact (e.g. thermostat, switch, etc.).
The valve is returned to its initial position in a currentless state by means of a return spring.
