J-VALVES
Design Features
Nickel-Aluminum Bronze Material:The valve body is made of ASTM B148 C95500 nickel‑aluminum bronze (CuNiAlFe), containing approximately 4.5% nickel and 10% aluminum. It provides excellent resistance to
seawater corrosion, cavitation corrosion, erosion and biofouling, with mechanical strength close to carbon steel, suitable for seawater, salt spray and chloride‑containing environments.
Two-Piece Design:The valve body consists of left and right sections, featuring a simple and compact structure for easy manufacturing, assembly and internal maintenance, reducing downtime and maintenance costs.
Floating Ball Design:The ball can float freely under medium pressure and tightly contacts the downstream seat to achieve reliable sealing. It delivers excellent sealing performance under low-pressure conditions with a simple and dependable structure.
Reduced Bore (2x1 1/2"):The valve end connection is 2 inches (DN50) with an internal flow passage of 1.5 inches (DN40). This design reduces valve weight, material consumption and operating torque while meeting most general flow control requirements, offering better economy than full-port designs.
Flanged Connection:RF (Raised Face) flanged connection conforming to ASME B16.5, pressure class 150LB
(PN20), providing high installation compatibility and stable sealing.
Anti-Static Device:Built-in anti-static spring/steel ball structure conducts static electricity between the stem and body, and between the ball and body, preventing safety hazards caused by static accumulation.
Blowout-Proof Stem:The stem is designed with a lower anti‑blowout shoulder, preventing the stem from being blown out by abnormal overpressure inside the valve and ensuring operational safety.
Lever Operation:Standard lever operator enables 90° quick opening and closing with simple and intuitive operation. A locking device can be fitted to prevent misoperation, ideal for frequent operation and local control applications.
Compact and Lightweight:The 2-inch nickel‑aluminum bronze construction results in a moderately sized, lightweight valve, easy to install in space‑restricted areas such as ship compartments, offshore platform pipe racks and skid‑mounted equipment.
Biofouling Resistance:The C95500 surface discourages marine organism attachment, reducing clogging and corrosion caused by biofouling and lowering maintenance frequency.

Advantages & Value
Excellent Seawater Corrosion Resistance:C95500 nickel‑aluminum bronze provides far better corrosion resistance in seawater than carbon steel and stainless steel, free from pitting, crevice corrosion and stress corrosion cracking. Service life exceeds 20 years, significantly reducing replacement costs in marine environments.
Cavitation & Erosion Resistance:High hardness and good wear resistance of aluminum bronze withstand cavitation corrosion and solid particle erosion caused by high‑velocity seawater flow, suitable for pump outlets and throttling locations.
Anti-Biofouling:Low marine organism attachment reduces clogging and corrosion, cutting cleaning and maintenance frequency as well as chemical treatment costs.
Economical & Practical:Reduced bore design lowers material consumption; 150LB low-pressure class covers most general applications, delivering outstanding cost‑performance among seawater‑resistant valves.
Balanced Strength & Corrosion Resistance:Tensile strength of C95500 exceeds 550MPa, approaching carbon steel, with superior corrosion resistance and no need for extra wall thickness allowance.
Easy Operation:90° lever operation is intuitive with low operating torque; locking device prevents misoperation, suitable for frequent local operation on ships and platforms.
Reliable Sealing:Simple and effective floating ball self‑energized sealing, combined with high‑performance PTFE/RPTFE seats, ensures long‑term leak‑tight service.
Convenient Maintenance:Two-piece construction with top-entry design allows inline replacement of seats and packing. Corrosion-resistant nickel‑aluminum bronze minimizes body replacement, reducing lifecycle costs.

Butterfly valves are widely used in industrial piping because of their compact structure and quarter-turn operation. Among different designs, Triple Offset Butterfly Valve and double offset butterfly valves have different sealing principles and application characteristics.
A Y Strainer provides an effective first line of protection by removing solid contaminants from the process medium before they reach downstream equipment. With a compact structure, relatively low flow resistance, and convenient screen access, the Marine Y Strainer is widely considered for seawater cooling, ballast systems, firewater systems, and other marine piping applications.
A Swing Check Valve is a mechanical valve designed to prevent reverse flow in industrial piping systems. Unlike manually operated valves, it works automatically according to the direction and pressure of the fluid, making it an important component for protecting pumps, compressors, pipelines, and other downstream equipment.
In industrial piping systems, solid particles, welding debris, rust, and other contaminants can negatively affect pumps, valves, heat exchangers, and instrumentation. A Y Type Strainer provides a practical solution by continuously filtering unwanted particles from the process medium before they reach sensitive downstream equipment.
