R-3710-1007 Johnson Controls RESTRICTOR

Overview

The Johnson Controls R-3710-1007 is a precision-engineered 0.007-inch aqua inserted restrictor designed to limit pressure and flow direction in pneumatic operating systems. This component is critical for creating a specific pressure drop within a pneumatic control loop, ensuring that master controllers receive accurate input signals while preventing excessive air consumption. Housed with a standardized compression fitting connection, it facilitates a secure, leak-proof mechanical seal on standard pneumatic tubing lines, maintaining stable modulation without the risk of clogging.

Features

• Precision Orifice: Calibrated 0.007-inch opening provides exact flow restriction for sensitive pneumatic pilot signals.
• Color-Coded Identification: Aqua surface coding allows technicians to quickly verify the 0.007-inch flow specification during field installation or maintenance.
• Robust Construction: Designed with an elastomeric O-ring, thermoplastic ferrule, and a zinc-plated compression nut for industrial reliability.
• System Stabilization: Minimizes signal fluctuations in controllers and actuators for smoother equipment modulation.

Specifications

• Orifice Size: 0.007 in. (0.18 mm)
• Connection Size/Type: 1/4 in. O.D. compression fitting
• Material: Thermoplastic ferrule, elastomeric O-ring, and zinc-plated compression nut
