Product catalog summary

Overview: This document provides technical specifications and details for roller-operated valves in the ER series, specifically models ER-25-310, ER-28-310, ER-18-310, ER-18-310-Q, ER-18-510, and ER-18-510-Q. These valves are available in 3/2-way and 5/2-way configurations with connections ranging from M 5 (10/32 UNF) to G 1/8, and flow rates between 80 to 320 Nl/min (0.081 to 0.325 Cv).

Specifications:

Function: The ER-25-310 and ER-28-310 models are 3/2-way and 5/2-way valves with spring return.
Connection: Available in M 5 (10/32 UNF) and G 1/8.
Nominal Size: 2 mm for ER-25-310 and 4 mm for ER-28-310.
Flow Rate: Ranges from 80 Nl/min (0.081 Cv) to 320 Nl/min (0.325 Cv).
Pressure Range: 0 to 12 bar (0 to 175 psi).
Actuating Force: Varies from 8 N to 18 N at 6 bar.
Temperature Range: -10 °C to +70 °C (+14 °F to +158 °F).
Materials: Body made of anodized aluminum, inner parts include aluminum, brass, and stainless steel. Seals are made of NBR and POM, with rollers and levers made of stainless steel, POM, and anodized aluminum.
Weight: Ranges from 0.044 kg (0.097 lb.) to 0.121 kg (0.267 lb.).

Design and Function:

For models ER-25-310 and ER-28-310, port 1 must be used as the pressure inlet.
Models ER-18-310 and ER-18-510 have interchangeable ports and are suitable for vacuum applications with order numbers ER-18-310-Q and ER-18-510-Q.

Dimensions and Operation:

The document includes dimensions for the ER series and describes the valve operation stages: pre-stroke (valve not actuated), working stroke, and end of stroke (bottomed).
Port functions are defined as pressure inlet, outlet, and exhaust for different models.
