FAQs of Lever Handle Waste Valve

1. What are the opening methods of the Lever Handle Waste Valve?

The opening mode of the Lever Handle Waste Valve is mainly a mechanical linkage structure driven by a lever, which is primarily divided into the following four categories.

• 1) horizontal toggle
  Operation mode: handle along the horizontal direction, left and right toggle. The lever is riveted to the valve rod by a pin, and the valve core is driven to move up and down by the lever principle when toggled.
• 2) vertical press
  Operation mode: The handle is in a vertical state (flush with the valve body surface or slightly convex). Press the top of the handle to open the drainage, and press again to rebound and close. Some models support a two-way operation, allowing for “press open + pull close” functionality.
• 3) rotary toggle
  Operation mode: The handle must rotate and toggle in a combined operation. First, rotate the handle counterclockwise to unlock. Then, toggle to the open position along the horizontal or vertical direction. Finally, rotate in the opposite direction to lock when closing.
• 4) folding lever type
  Operation mode: The lever can be folded and stored for easy use. When in use, the handle can be unfolded for toggle operation.

2. What materials are available for the Lever Handle Waste Valve body?

The Lever Handle Waste Valve can be made from different materials to match different uses, liquids, and budgets. These materials include PVC-U, ABS plastic, H59/H62 brass, 304 stainless steel, and 316 stainless steel.

1. PVC-U material has strong corrosion resistance, low cost, is suitable for ordinary household cold water drainage scenarios, and can withstand weak acid and alkali media.
2. ABS engineering plastics have excellent toughness and strong impact resistance, suitable for commercial kitchens, public toilets, and other high-frequency use environments, and may be used in a slightly collision-prone environment.
3. H59/H62 brass material has good sealing performance and high temperature resistance (≤ 120 ℃). After lead-free treatment, it conforms to EU RoHS and US NSF 61 standards. It is suitable for high-end bathrooms, hot water drainage systems, and drinking water-related scenarios.
4. 304 stainless steel material has outstanding anti-rust performance, suitable for wet, mild corrosion environments, such as residential and commercial buildings.
5. 316 stainless steel adds the molybdenum element to 304, and the corrosion resistance is greatly improved.

3. Does the stainless steel Lever Handle Waste Valve support magnetic detection?

You can check the stainless steel lever handle wastewater valve with a magnet. A 304 stainless steel valve is usually not magnetic or only a little.

During production, the valves are carefully tested. This makes sure the stainless steel is pure and strong, and that the valve does not rust or get damaged.

4. Can the Lever Handle Waste Valve be used in drainage scenarios with corrosive liquids?

The Lever Handle Waste Valve can be used with corrosive liquids. You should pick the material based on the type, strength, and temperature of the liquid:

PVC-U can handle weak acids and bases with a pH of 4–10. It works for ordinary commercial kitchens, hospital toilets, and similar places.

ABS plastic is stronger against corrosion and can handle medium or mild corrosive liquids with a pH of 3–11.

316 stainless steel is best for strong acids and bases. It has added molybdenum, which makes it very corrosion-resistant and able to handle liquids with pH 1–13.

5. What is Lever Handle Waste Valve packaging?

The Lever Handle Waste Valve is packed as one set per box. Each set goes into a plain white box with foam or pearl cotton inside to protect it from shocks. The box also includes installation instructions, extra gaskets, and other needed accessories.

Every 20–30 sets are put into a strong five-layer corrugated outer box. The outer box has labels showing the product model and marks for moisture and fragile items. This helps the boxes resist drops and pressure during long shipping by sea or air.

Customized packaging is also available. It can meet minimum order needs and support customer branding or overseas market requirements.

6. Does Lever Handle Waste Valve support third-party inspection?

The Lever Handle Waste Valve can be checked by third-party testing companies. Customers can choose companies like SGS, Intertek, BV, TÜV, or other trusted international testers.

Tests can check the material, sealing, corrosion resistance, strength, and other important features. After testing, we provide a full third-party report. This report can be used for product certification, market approval, or project bidding.

7. What is the connection between the lever handle and the valve stem of the Lever Handle Waste Valve?

The lever handle and stem of the Lever Handle Waste Valve are connected in two main ways. The standard model adopts a stainless steel pin riveting process. The pin passes through the reserved hole of the handle and valve stem and is fixed at both ends. The connection strength is high. It can withstand ≥ 10,000 repeated opening and closing tests and is not easily loosened or broken. The high-end customized model adopts integrated injection molding or welding fixation. The handle and valve stem are seamlessly connected. The mechanical strength is better and suitable for commercial high-frequency use scenarios.
