Hydraulic Counterweight Valve
Energy‑Efficient Flow Balancing & Pressure Holding – Hydraulic Counterweight Valve YF15‑01 Hydraulic systems in heating, cooling, and industrial applications require precise flow balancing, pressure holding, and energy efficiency. The hydraulic counterweight valve from Flying Bull (Model YF15‑01) is a cartridge‑style power unit pressure‑maintaining valve, available alongside the RV15‑01 direct relief valve and general hydraulic cartridge valves. It operates with oil as the medium. The valve is 100% brand new, manufactured in Zhejiang, China, and backed by a 1‑year warranty. Delivery takes 5–7 working days. Product range and installation features The product range includes hydraulic counterweight valves, specifically the RV15‑01 direct relief valve, the YF15‑01 cartridge‑style power unit pressure‑maintaining valve, and general hydraulic cartridge valves. These can be further categorized into static balance valves, dynamic balance valves (including dynamic flow and dynamic differential pressure types), and self‑operated balance valves. The YF15‑01 model features a plug‑in design for easy integration into power units. These valves automatically regulate flow and pressure based on actual demand, helping to minimize energy waste, improve efficiency, and reduce operating costs in heating, refrigeration, and similar systems. Static balance valves address system resistance imbalances, while dynamic balance valves maintain consistent flow or pressure differentials despite system fluctuations, meeting diverse application needs for wholesalers and their customers. How the different balance valve types work Static balancing valve – Sets a fixed flow capacity (Kv) during system commissioning. It ensures each branch receives the correct proportion of flow according to design requirements. Dynamic balancing valve – Automatically adjusts valve resistance based on system pressure changes to maintain constant flow under varying loads. Pressure‑independent balancing valve – Combines both functions; maintains constant flow regardless of pressure fluctuations. Operating pressure The valves are designed for standard operating pressure and are suitable for conventional hydraulic systems. They are not intended for specialized high‑pressure or low‑pressure environments, simplifying the product selection process for wholesalers when matching valves to their customers' system requirements. Certifications and patents All products are CE certified and comply with EMTEX and DTEX standards. The company holds design patents, invention patents, and utility model patents, demonstrating strong technical capability and full regulatory compliance. These qualifications enhance the market competitiveness and credibility of the products supplied to wholesalers.

Company Introduction
Frequently Asked Questions (FAQ)
1. What types of hydraulic counterweight valves does FLYING BULL offer, and what are their core functions?
FLYING BULL provides hydraulic counterweight valves including RV15‑01 direct acting relief valves, YF15‑01 cartridge power unit pressure holding valves, and hydraulic cartridge valves. They can be further divided into static balancing valves, dynamic balancing valves (including dynamic flow balancing valves and dynamic differential pressure balancing valves), and pressure‑independent balancing valves. The core function is to automatically adjust water flow and pressure according to actual needs to avoid energy waste; static balancing valves eliminate system resistance imbalance, while dynamic balancing valves maintain constant flow or pressure difference with system changes, suitable for heating, cooling and other systems to improve energy efficiency.
2. What key basic information is available for FLYING BULL's hydraulic counterweight valves (e.g., OE number, medium, origin)?
The OE number of the hydraulic counterweight valve is YF15‑01. The applicable medium is oil, and all products are 100% brand‑new with high quality. They are produced in Zhejiang, China, providing wholesalers with clear and reliable product source information.
