90mm Plastic Ball Valve Quarter Quick Open Close for Aquaculture Water Pipeline
90mm corrosion resistant plastic ball valve with fast 90° switch, used for seawater aquaculture, chemical wastewater & swimming pool piping system.
Description
I. Product Function
The 90mm valve is a plastic ball valve manufactured primarily from UPVC or PP. With a quarter‑turn (90°) operation, it provides rapid opening and closing. Its true union ball valve configuration facilitates easy disassembly for inspection and maintenance, while the full port ball valve design guarantees high‑volume flow with minimal restriction. This valve is tailored for plastic piping with a 90mm outside diameter, enabling quick connection or isolation of seawater, acid/alkaline waste, recirculating fluids, and similar media. It serves as an effective emergency shut‑off and zone‑separation device in aquaculture, chemical processing, and swimming pool systems.
II. Specification Table

The valve body is integrally injection‑molded from anti‑corrosive plastic, protecting it from salt in seawater and mild acidic media. The handle requires only a quarter‑turn to go from fully open to fully closed, allowing emergency shutoff during line faults or equipment servicing to prevent continuous leakage. The true union structure permits valve disassembly and seal replacement without cutting pipes, simplifying maintenance.
III. Common Applications
-
Seawater aquaculture circulation lines
-
Acid/alkali transfer pipelines in electroplating parks
-
Large commercial pool water recirculation
-
Main agricultural irrigation mains
-
Wastewater treatment plastic piping
-
Laundry effluent conveyance lines
IV. Practical Deployment Case
At a large‑scale seawater aquaculture recirculation facility in Surabaya, Indonesia, the entire seawater supply main for the breeding farm was laid with 90mm plastic pipes, equipped with a batch of 90mm valves. The farm periodically rotates culture ponds and maintains filtration equipment. Thanks to the valve’s rapid response, operators can instantly cut off seawater to specific sections, eliminating lengthy depressurization and drainage procedures. Maintenance downtime has been reduced by 60%. The PP valve bodies resist saltwater corrosion, showing no aging or leakage even after prolonged immersion in seawater, ensuring stable operation of the aquaculture recirculation system.
V. Frequently Asked Questions for Overseas Purchasers
Q1: Does the quick open/close action of the 90mm PVC ball valve risk water hammer damage to the pipeline?
A1: Under normal operation with temperate water in aquaculture or pool systems, standard opening/closing does not generate significant water hammer. For high‑pressure lines, we offer an optional model with a cushioned handle, which allows slower actuation to mitigate any water hammer concerns.
Q2: For long‑term use in Indonesia’s marine environment, should I choose UPVC or PP material?
A2: For general seawater circulation, UPVC offers better cost‑effectiveness. If the service involves elevated temperatures or intermittent exposure to mild acid/alkaline chemicals, we recommend PP for its superior aging resistance.
