Unlike traditional swing checks, Ball Check Valves utilize a spherical closing element. This design is particularly superior for viscous fluids and wastewater, as the rotating ball provides a "self-cleaning" action, preventing debris accumulation and ensuring a bubble-tight seal every time.
High-quality manufacturers now utilize Hastelloy, Duplex Stainless Steel, and NBR/Viton-lined balls. These materials offer unprecedented resistance to hydrogen sulfide (H2S) in oil and gas applications, extending the valve lifecycle by up to 300% in corrosive environments.
By optimizing the flow path geometry, modern ball check valves minimize pressure drops (Low Delta-P). Our engineering focus ensures that fluid turbulence is reduced, which directly translates to lower pumping energy costs for the end-user.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has long been engaged in international trade business, mainly a variety of pipes, carbon steel, alloy steel, stainless steel material, seamless pipe, straight seam welded pipe, spiral welded pipe and matching pipe fittings.
Manufacturing standards for ASTM, ASME, EN, JIS and so on, in line with international standards. We are providing good quality, price competition, timely delivery, and perfect service! Our chairman, Mr. Ming SUN, is a strong environmentalist and a fan of technological innovation, driving our focus towards clean energy and sustainable manufacturing.
The next decade of valve technology revolves around "Smart Flow". We are researching sensors embedded within the valve body to monitor real-time pressure, ball position, and wear-and-tear levels, enabling predictive maintenance via AI algorithms.
Following our participation in the Dubai COP28 Conference, our R&D is focused on zero-emission sealing technologies. We aim to support the global "Double Carbon" goals by providing valves that eliminate methane leaks in natural gas pipelines.
As the Hydrogen economy grows, we are developing valves capable of operating at -253°C. These require specialized austenitic stainless steels and unique ball-seat interface geometries to maintain seal integrity.
High-pressure ball checks for fracking fluid management and sand slurry transport where durability is non-negotiable.
Large-diameter solutions for sewage treatment plants, preventing backflow in lift stations with minimal maintenance.
PTFE-lined ball valves for aggressive acid handling and corrosive chemical transfer lines.
Supporting vertical axis wind power projects and rail maglev cooling systems with specialized fluid control.
In the post-pandemic era, Supply Chain Resilience has become the #1 priority for global enterprises. Shaanxi Kerlimar leverages China's advanced manufacturing ecosystem to provide:
We provide localized technical documentation and multilingual support to ensure our European and North American clients meet regional installation codes.
Our products strictly adhere to:
• API 6D (Pipeline Valves)
• ASME B16.34 (Valves-Flanged, Threaded)
• CE/PED (Pressure Equipment Directive)
Following our commitment at the China-Finland High Technology Match Conference, we provide full transparency on the carbon footprint of our manufacturing process.
A: Ball check valves feature a non-clog design. The ball rotates during operation, which creates a scouring effect that prevents solids from settling. This makes them ideal for mining and wastewater, where swing checks often fail due to hinge-pin obstruction.
A: Maintenance is minimal. Because there are no complex levers or pins, the primary task is inspecting the ball and seat for wear. Most of our designs allow for "top-entry" maintenance, meaning you can service the valve without removing it from the pipeline.
A: Yes, ball check valves are excellent for vertical-up flow. The weight of the ball combined with backpressure ensures a positive closure when flow stops, preventing water hammer and backflow effectively.
A: Every valve comes with a 3.1 Material Certificate. We track the heat number from the steel mill through our manufacturing process to the final product, ensuring 100% accountability for alloy composition.
In December 2023, we were invited to participate in the Dubai COP28 Conference. We are currently completing 10KW-500KW series of small units before landing experiments, will actively participate in the "thousands of wind action", with the help of this series of technology efficiency, low cost, high reliability, and high security. These features will become an indispensable part of new productivity, making outstanding contributions to rural revitalization and the global 1.5°C temperature control goal.
