Aug 29 2025Bi-Directional Sealing Centerline Butterfly Valve Solves Pipeline Backflow Puzzles
JRVAL, a premier butterfly valve manufacturer, has unveiled a game-changing structural innovation that equips its entire range of soft-seated butterfly valves with true bi-directional sealing capabilities, eliminating backflow risks at no extra cost to customers.
In a significant advancement for the flow control industry, JRVAL announced today that all its soft-seated centerline and high performance butterfly valves (HPBV) will now feature full-pressure bi-directional sealing as a standard. This development addresses a long-standing challenge where conventional resilient seated valves often fail to provide a reliable seal against reverse flow or back pressure. This upgrade, which comes at no additional cost, is aimed directly at supporting small and medium-sized enterprises (SMEs) seeking high-reliability industrial valve solutions without the premium price tag of a complex triple offset butterfly valve.
The innovation stems from a proprietary modification to the valve's sealing structure. "This isn't about adding components; it's about perfecting the design through superior manufacturing," said the founder of JRVAL, a recognized casting expert with over 20 years of experience. "Only a true source butterfly valve factory with integrated control over butterfly valve casting, precision valve machining, and final butterfly valve assembly can achieve this level of engineering. We are passing this efficiency and performance benefit directly to our clients."
The Challenge: Unidirectional Limitations in Critical Applications
For decades, many standard soft-seated valves, such as the widely used wafer type butterfly valve and lug type butterfly valve, were primarily designed for unidirectional shutoff. In systems where backflow can occur, operators either had to install the valve in a specific orientation or invest in more expensive solutions like a double eccentric butterfly valve or even a gate valve. This limitation posed risks in applications ranging from HVAC and water treatment to general industrial processes, where preventing reverse flow is critical for equipment protection and system safety.
The Solution: Engineering Excellence from a Foundry Expert
JRVAL's solution redefines what is possible for a centerline valve. By leveraging their deep expertise in casting, the company ensures that every valve body, whether a stainless steel butterfly valve (like a butterfly valve ss316) or a carbon steel model, has a flawless material foundation. This is followed by state-of-the-art CNC butterfly valve machining, adhering to what the company calls "专标专供" (special standards for special supply). This precision guarantees perfect geometry at the seat and disc interface, which is the key to achieving a tight, reliable bi-directional seal.
This upgraded performance is now standard across their entire soft-seated portfolio, including:
- Wafer style butterfly valve and Lug style butterfly valves
- Double flanged butterfly valve models
- Valves with various seat materials like the EPDM seat butterfly valve and PTFE lined butterfly valve
- Manual versions (butterfly valve with handle) and automated packages (pneumatic butterfly valve, electric actuated butterfly valve)
Empowering SMEs with High-Performance, Cost-Effective Valves
By making this technology a no-cost standard, JRVAL solidifies its position as a leading china butterfly valve manufacturer focused on the SME market. "Our target clients are businesses that cannot compromise on quality but are smart about their investments," the founder added. "They need a reliable industrial butterfly valve that performs like one from a major brand, and our new bi-directional sealing technology delivers exactly that. Whether it's a 4 inch butterfly valve for a local utility or a 12 inch butterfly valve for a manufacturing plant, the performance is guaranteed."
This innovation ensures that any butterfly valve valve from their factory provides enhanced system integrity, simplifies pipeline design, and offers peace of mind against the challenges of back pressure, making it a superior choice when comparing a butterfly valve vs ball valve for shutoff applications.
The Foundry-First Advantage
Our roots are in casting. Led by a casting expert, we guarantee every butterfly valve casting meets or exceeds international standards (e.g., ASME, DIN). This control over raw materials, from a wcb butterfly valve to a cf8m butterfly valve, ensures superior mechanical strength and a defect-free foundation for every valve we produce.

Broadened Applications with Bi-Directional Reliability
Our standard bi-directional sealing enhances performance and safety across numerous industries, making our valves a more versatile and reliable choice for your flow control needs.
HVAC & Chilled Water Systems
An hvac butterfly valve must handle fluctuating pressures. Our bi-directional seal prevents backflow in balancing and isolation duties, protecting pumps and chillers.
Water & Wastewater Treatment
Reliable shutoff is crucial. Our water butterfly valve, from a 2 inch butterfly valve to a large diameter one, ensures no backflow of contaminated water, improving plant safety.
Marine & Shipbuilding
In ballast and cooling systems, a marine butterfly valve must be robust. The secure bi-directional seal is vital for vessel stability and safety, especially in lug and wafer type butterfly valve formats.
General Industrial Processes
From chemical processing to food and beverage, preventing cross-contamination is key. A sanitary butterfly valve or a resilient lined butterfly valve with our seal provides an extra layer of process security.
