E-7 Valve Class 1:
Valve Body: Aluminum
Elastomers: Viton O-rings, PTFE Seal, Acetal Wear Rings
Pilot Control System: Brass solenoids and fittings with flared copper

E-7 Valve Class 2:
Valve Body: Anodized Aluminum
Elastomers: Viton O-rings, PTFE Seal, Acetal Wear Rings
Pilot Control System: Stainless steel solenoids

Design Features

Electronic valves integrate with LectroCount Electronic Registers, providing flexible control and greater accuracy in deliveries. These two solenoid valves provide a low-volume dwell period to eliminate hydraulic shock and improve the accuracy of a preset delivery.

Solenoid Block Valve:
Provides simple on/off operation typically applied for security purposes to prevent unauthorized operation.

Two-Stage Control Valve:
Provides system security and prevents unauthorized operation. Slow closing microprocessor controlled valve, allows for preset, net and/or gross volume, and/or price.
