DATASHEET INVA 32

Product catalog summary

Overview: This document is a datasheet for a 3-way, 2-position vacuum/vacuum breaker or diverter valve. It provides specifications, operational modes, and additional options for customization.

Specifications:

Sizes: Available in 1”1/2, 2”, and 2”1/2.
Pipe Threads: F/F/F gas ISO228.
Actuator Types: Single Acting with electric actuator only, Double Acting with pneumatic actuator only.
Temperature: Maximum operating temperature is +140°C, with an ambient temperature range of 0 to +60°C.
Materials: Valve body and seal holder are made of anodized aluminium; shutter seal is FKM.

Optional Features:

ATEX certification for pneumatic drive type.
2 reed sensors limit switch-box.
PTFE shutter seal.

Functions:

Vacuum/Vacuum Breaker Function: Operates with vacuum pumps (pneumatic drive only).
Diverter Function: Operates with blowers.

Actuator Details:

Pneumatic Actuator: Requires a pilot pressure of 4 to 6 bar.
Electric Actuator: Operates at 24 VDC with a power coil of 23 A and a holding coil of 0.28 A.

Operation Chart:

Vacuum Mode: Utilizes a vacuum pump to draw from service to the vacuum pump.
Vacuum-Breaking Mode: Uses a blower to direct flow from the vacuum pump to service.

Dimensions and Pressure:

Minimum absolute pressure is 5 mbar for most models.
Dimensions vary slightly between models, with lengths ranging from 315 mm to 333.5 mm.
