Ball valve plastic 1 1/2" FF (internal-internal thread) China (white)
Plastic ball valve 1 1/2" BSP is a reliable, high-strength, and highly cost-effective full-bore valve element with internal threading on both sides. It is designed for quick and convenient connection of flexible Layflat (LFT) hoses to distribution or main pipelines, as well as for regulating or completely shutting off water flow in the main branches of drip irrigation and automatic watering systems. The smooth plastic ball ensures complete sealing of the design, resistance to salt buildup, and smooth handle movement.

Plastic ball valve 1 1/2" FF: Reliable shut-off valve for Layflat hoses and main lines
Do you want to create an efficient, reliable, and affordable water distribution system on your site? A plastic ball valve with a two-sided internal thread (FF) of an average main diameter1 1/2" (one and a half inches)is one of the best solutions for equipping modern high-power irrigation systems. Unlike brass or cast iron counterparts, this polymer fitting is completely resistant to corrosion, does not rust from constant contact with moisture, and is fully inert to chemical fertilizers, which are often introduced through drip irrigation.
This valve is an essential element when building flexible pipelines, where distribution lines are connected to Layflat (LFT) hosesLayflat (LFT)using the corresponding threaded couplers and adapters. The full-bore design with a diameter of 1 1/2" guarantees minimal hydraulic resistance and maximum pressure preservation from the pumping station.
Key advantages of the plastic valve 1 1/2" FF:
Plastic shut-off mechanism: The internal ball is made of a special engineering plastic with an ideally smooth surface. It does not "stick" due to hard or muddy water and is not covered with limestone or salt deposits. This ensures smooth movement of the valve handle even after a long winter downtime of the system.
Reliable sealing: A well-thought-out system of internal gaskets-seals provides a tight fit of the shut-off ball, completely excluding water leakage and loss of working pressure in the distribution line.
Lightweight and robust design: The small weight of the polymer body does not overload the plastic pipes and flexible Layflat hoses, protecting them from sagging, deformation, and bending at the connection points during system filling with water.
UV stabilization of the material and aesthetic appearance: The white plastic contains special additives that protect the valve from destruction and cracking under the influence of direct sunlight during open mounting in fields, gardens, or industrial greenhouses.
Scope of application:
Connection and branching of flexible Layflat (LFT) hoses with distribution and main pipes through threaded adapters.
Organization of zonal manual control of large irrigation blocks, drip irrigation sectors, and fogging.
Use in main nodes of household water supply, connection to storage tanks, eurocubes, and pumps.
Equipping of system blowdown nodes with compressed air and quick water drainage from the main line before winter conservation.

Installation tip from Agras.ua:When assembling plastic threaded nodes, be sure to use high-quality sealing materials - FUM tape or sanitary thread Koer, winding it on the external thread of the counter fitting strictly clockwise. To avoid damaging the plastic threads, tighten the valve tightly by hand. If additional tightening with a tool is necessary, do it extremely carefully, without excessive lever effort.
