T/S1710 Circuit Balancing Valve NPI

Product catalog summary

Overview: The document provides technical specifications and features of NIBCO's Circuit Balancing Valves, specifically models T1710 and S1710, designed for HVAC and plumbing systems. These valves are engineered to ensure optimal flow distribution and system performance, contributing to energy and cost efficiencies.

Key Features:

Dezincification resistant brass body, bonnet, and trim to prevent corrosion.
Two integral test ports for differential pressure measurement.
Memory stop feature and position display window on the handwheel for ease of use.

Applications: These globe-style balancing valves are suitable for HVAC and plumbing systems, ensuring a balanced system for a comfortable indoor climate.

Design Criteria:

Complies with ANSI B1.20.1 for NPT ends and ANSI B16.18 for solder ends.
Unique straight pattern globe design for improved flow measurement accuracy and lower head loss compared to 'Y' pattern globes.

Materials & Construction:

Body, isolating stem, regulating stem, bonnet, disc nut, and disk seat ring made from DZR metal.
Handwheel made from polymer and stem seals from EPDM.

Technical Specifications:

Rated at 240 psi to 250°F.
Non-rising stem design with integral internal memory stop.

Dezincification Resistance: DZR metal is used to prevent dezincification, a form of corrosion that affects brass when exposed to aggressive waters. This material ensures the mechanical strength and longevity of the valves.

Dimensions and Weights: The document includes a detailed table of dimensions, weights, and quantities for different valve sizes, ranging from 1/2 inch to 2 inches.
