With abundant experience, we warmly welcome you to wholesale premium pvc true union ball valve with vented ball type for sale here from our factory. Quality products and reasonable price are available.
1. Products Introduction
The PVC true union ball valve is one of the most commonly used valves in industrial piping systems, and SANKING's valves outperform competitors in terms of overall sealing performance, with very low operating torque and simple operation. During the design process, SANKING has considered all possibilities, thus in addition to the regular product, a vented ball type is an optional solution. The vented ball design allows gas to escape from the ball cavity, avoiding pressure from building up and causing the ball to stick. This is especially essential in applications involving the transfer of gas-filled media.

FAQ
Q1: How long is the lifetime of Sanking's PVC ball valve
A: It varies according to different working conditions, if the conveyed liquid is pure water at 25 degrees with a pressure of 3 kgs, indoor application, the service life can exceed 50 years. But if it is 98% concentrated sulfuric acid at 25 degrees with a pressure of 3 kgs, indoor application, the service life is often about 3 years.
Q2: What kind of valve should be used for 30% nitric acid at 70 degree with a pressure of 3KGS?
A: It is recommended to use CPVC valves with black VITON seal.
Q3: What is the protocol for requesting a manufacturing quote from SANKING?
A: Write to us with your purchase request. Be sure to include all accessories in your request for quote.
Q4: How are orders packed and shipped ?
A: SANKING normally pack goods into master cartons with pallet if needs.Most shipments include boxes packed inside an outer carton.
Q5: What are your quality control procedures?
A: SANKING adheres to strict quality control procedures that begin with product design and carry through to the end of the production process using state-of -the-art quality control equipment.
Sodium hypochlorite service is not a normal clean-water valve job. The main trouble is not only corrosion. It is gas release, trapped pressure inside the valve cavity, crystallization around the seat area, and higher operating torque after the valve stays closed.
For water treatment equipment builders, chemical dosing skid manufacturers, pool system contractors, and disinfection project buyers, the valve should be selected around the real working condition of the NaClO line.
