How can we do if the plastic ball valve too tight
PVC True Union ball valves are available in sizes ranging from ½” to 4”, providing a convenient and effective way to control system flow. The valve can be easily opened or closed by simply turning the plastic handle a quarter turn. These valves feature double union joints, making them easy to service and maintain, whether repairing or replacing them. The main part of the valve, called the bracket, houses the handle and ball and can be removed from the line for easy service without disassembling the entire system. True Union ball valves are available with socket or threaded ends and it is recommended to use PVC glue or thread tape when installing the valve in the pipe. These valves are extremely durable and tested to withstand pressures up to 150 PSI, making them suitable for use in industrial applications where quick response and ease of repair are critical.
Do you know the venturi fertillizer
The Venturi fertilizer injector and micro-irrigation system are installed parallel to the water supply pipe control valve at the entrance to the irrigation area. When the control valve closes, a pressure difference is created, causing water to flow through the venturi fertilizer injector. This flow creates a vacuum in the venturi tube, drawing the fertilizer solution from the open bucket into the pipe system for fertilization.

What could we do if the valve doesn't closing tightly?
In general, if it is a case of not closing tightly, first confirm whether the plastic valves has been closed in place, if there is still a leak that can not be sealed after it has been closed in place, then check the sealing surface again. Some PVC valves have removable sealing pairs, so take them out for grinding and test them again. If the valve is still closed, it must be returned to the factory for repair or replacement of the valve, so as not to affect the normal use of the valve and the emergence of industrial accidents and other problems.
