1. Products Introduction
SANKING PVC Gate Valves are designed not only for reliable on/off flow control in piping systems but also as fine adjustment valves when paired with a full bore ball valve at the front end. The screw-type rising stem structure allows more precise control of liquid flow, making them versatile for both industrial and compact applications.
With their lightweight design, compact structure, and clean appearance, SANKING UPVC Gate Valves are especially suitable for use in aquariums, aquaculture systems, and other confined spaces where space-saving and aesthetics matter, in addition to traditional industrial uses.
Currently available in 1/2" to 2" (DN15–DN50) sizes under DIN and ANSI standards, these valves offer smooth operation, tight sealing, durability, and easy installation.
2. Main Features
Lightweight & Compact: Easy to handle, install, and perfect for tight installations such as aquariums or fish tanks.
Attractive Design: Clean and modern appearance suitable for visible piping systems.
Durable Material: High-quality UPVC with excellent corrosion and chemical resistance.
Reliable Sealing: Elastomer sealing system ensures zero leakage during operation.
Precise Flow Control: Screw-type rising stem structure enables fine adjustment, especially effective when paired with a ball valve.
Low Flow Resistance: Straight-through flow path design minimizes pressure loss.
Weather Resistant: UV stabilizers improve aging resistance for long service life.
Quality Control: Every valve is strictly pressure- and sealing-tested before delivery.

8. FAQ
Q1: How much pressure can a PVC true union ball valve hold?
150psi.
Q2: Can the handle of the PVC true union ball valve be replaced?
Yes, it can be replaced easily. And this handle can be used as a tool for disassembly, assembly or adjustment of the support of the ball seat carrier.
Q3: How long is the lifetime of Sanking's PVC ball valve
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.
Q4: 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.
Q5: Are there any more economical suggestions for the pressureless delivery of copper sulfate solution at room temperature?
A: You can use PPH valve with EPDM gasket, pay attention to the crystallization problem.
Q6: Are your PVC true union ball valves reliable?
Yes, because we are using the nano molded material to ensure the reliability.
We are the first company in China to use CNC to process its core (ball sphere), to make sure there is no leakage
100% inspection before package.
Q7: Can we use the true union ball valve to control flow?
Yes, according to the different opening angles, the flow is adjusted non-linearly. If linear adjustment is required, the linear flow sphere needs to be replaced..
