GF-SBV-02

Static Balancing Valve

The GF-SBV-02 is a brass static balancing valve designed for hydronic heating and cooling systems. It supports manual flow balancing and commissioning to help achieve the required flow distribution across HVAC water circuits.

Overview

Product Overview

GF-SBV-02 is a brass static balancing valve with threaded connections, used for flow regulation and hydraulic balancing in HVAC water systems. The valve opening is set by handwheel, and flow is measured and set across the test ports, so that each branch can be brought to its design flow rate.

The valve is intended for building heating, chilled water and other closed-loop water systems, and is particularly suited to circuits where flow must be pre-set, measured and verified during commissioning.

In multi-branch systems, unequal pipe resistance leaves some branches carrying more than design flow while others fall short. GF-SBV-02 supports hydraulic balancing through flow regulation and measurement, reducing excess flow and improving distribution between branches, which gives the system a stable basis for operation.

Standard body material: brass HPb59-1 (GB/T 5231; Cu 57–60%).

Other grades: CW617N (CuZn40Pb2; EN 12164 / EN 12165) and CW602N, a dezincification-resistant brass. Both are available on request and must be stated on the order. We do not substitute a different grade without your written approval.

Minimum order quantity: applies to all three grades.

Lead content: all three are leaded brass. For potable water, confirm the lead-leaching limits of the destination market before ordering.

Material certificate: EN 10204 3.1 on request. The grade stated on the certificate governs.

OEM and Customization Options

GOFIVAL supports B2B sourcing and OEM cooperation for HVAC control valve applications.

We work with established manufacturing partners to coordinate product selection, technical documentation, packaging requirements and project-specific supply arrangements.

Private label, neutral supply and other customization requests can be discussed according to the required order quantity and technical specifications.

Contact GOFIVAL with your target valve size, flow requirements, actuator specifications and estimated order quantity for further evaluation.
