FAQs of Long Handle Drain Valve
1. How is Plumberstar’s long-handle drain valve manufactured?
Plumberstar long-handle blowdown valves are made with standardized, precision manufacturing processes.
The valve body is crafted from high-quality national standard brass. We can also customize it with 304/316 stainless steel as per your requirements. The long handle uses an engineering plastic + metal inner core composite structure. It keeps the handle strong, while also making it comfortable to operate and durable to use. All raw materials undergo two rigorous tests upon arrival at the factory: spectral composition analysis and hardness testing.
Brass valve bodies are formed with a hot forging one-piece process, boosting overall structural strength and pressure resistance. Stainless steel valve bodies are made through precision stamping + welding, and all welds are polished to keep the surface flat and the structure reliable. After forming, the valve body is processed with high-precision CNC machines for turning, drilling, and threading.
Every long-handle blowdown valve undergoes a 100% inspection of the finished product. Each product must pass a water-pressure sealing test, with pressure-holding detection at rated pressure to confirm no leakage and no pressure drop. At the same time, key indicators such as long-handling operation feel, valve body appearance, and thread precision are checked. Any unqualified products are marked immediately and sent for rework. This ensures that only fully qualified products reach the packaging and shipping stage.

2. What is the difference between a long-handle drain valve and an ordinary drain valve?
The difference between long-handle drain valves and ordinary drain valves lies in their use and use scenarios.
Long-handle drain valves have a long handle that can be manually opened or closed from farther or higher. The valve is suitable for installation at the bottom of the equipment or in narrow spaces, which makes operation easier and safer. Ordinary sewage valves are generally designed with only a short handle or knob, so it is inconvenient to operate in narrow or hard-to-reach places.
In some industrial uses, the handle length of a long-handle blowdown valve can also be made longer or shorter to fit the site. Ordinary blowdown valves usually have a fixed handle and offer less flexibility.
3. Can the pharmaceutical industry use this long-handle drain valve?
Plumberstar long-handled drain valves work well for pharmaceutical-related working conditions. The valve body is made of 316L stainless steel, which has strong corrosion resistance. The sealing parts use safe, non-toxic materials, fitting the common medium environments in the pharmaceutical industry and meeting the basic use needs of pharmaceutical applications.
The inner and outer surfaces of the stainless steel valve body are smooth, and the structure is easy to clean and rinse. This can effectively lower the risk of dirt and microbial residues. With proper process design and cleaning steps, the product meets GMP’s basic hygiene and cleanability requirements for equipment. It’s suitable for discharge stations for waste liquids, wastewater, and non-product-contact media in pharmaceutical production processes.
4. Can you provide long-handle drain valve samples?
Of course. Plumberstar long-handled blowdown valves are available for sampling, and we fully support your testing and quality verification needs. All samples are made with the same materials and manufacturing processes as mass-produced products, so they truly reflect the actual quality of your future bulk orders.
For projects with personalized needs—like logo engraving, handle length adjustment, interface spec customization, or surface treatment optimization—we can make exclusive samples for you based on the drawings or parameters you provide.
Once samples are finished, we’ll provide the corresponding test reports right away. We only start mass production after confirming all key indicators meet the required standards.
For our cooperative customers, Plumberstar has a sample fee reduction policy. After you sign the subsequent mass production order, the sample fee can be directly deducted from your payment for goods. This effectively cuts down your initial testing and verification costs.
5. What is the payment for the long-handle drain valve?
Plumberstar’s payment terms for long-handle blowdown valves depend on the order type and how we work together.
For regular export orders and new customers, we usually ask for a 30%–50% deposit. The balance is paid before shipment. The deposit is used to prepare materials and reserve production time.
For long-term customers with stable cooperation, the payment terms can be more flexible. For example, a 20% deposit, payment after seeing the bill of lading copy, or even quarterly settlement, based on agreement.
If payment is made by L/C, the terms will follow the letter of credit rules, which are usually linked to shipment and document submission.
The final payment method is decided based on the order value, customer credit, and discussion between both sides.
6. What’s the replenishment order process for long-handle blowdown valves?
Long-handle blowdown valve replenishment order processing flow:
Customers submit the original order number, product specifications, and replenishment quantity of demand. We check the history of cooperation information and inventory status after rapid feedback quotation and delivery.
After everything is confirmed, the customer makes the payment as agreed. Existing customers can continue using their usual payment method. We then arrange production or prepare the required documents at the same time. If the product is in stock, delivery can be arranged within 48 hours. If production is needed, the order will be completed according to the agreed production schedule.
After delivery, the logistics information and bill of lading will be pushed in real time. After the customer signs, we will follow up on the acceptance situation. The whole process will be synchronized by the dedicated docking person to ensure efficient connection.
7. How many years of drain valve production experience does Plumberstar have?
Plumberstar Factory has been making valves for almost 20 years. It has more than 15 years of experience making long-handle blowdown valves. Our factory can produce both standard valves and custom designs. These valves are used in industries like chemicals, medicine, and energy. Many customers from over 50 countries have used these products and trust their quality.
8. Can the long-handle drain valve structure be customized?
We can change and customize the long-handle blowdown valve based on your project drawings.
