As a professional manufacturer with years of experience in industrial valve production, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our high-performance DN150 DIN 3202 Stainless Steel Butterfly Valve. Engineered for reliability and durability in demanding applications, this valve is designed to provide superior flow control for a wide range of industries. We understand the critical need for dependable fluid handling components, which is why we focus on precision manufacturing and quality materials. This specific model, featuring a 316L stainless steel disc and a PTFE seat, offers an excellent balance of corrosion resistance and sealing performance, making it a versatile solution for your piping systems.
This butterfly valve is constructed to meet the rigorous DIN 3202 standard, ensuring compatibility and performance expectations are met. The wafer-style connection design allows for easy installation between flanges, saving space and reducing overall system weight. Here are the key features and technical specifications that set this valve apart:
- Robust Construction: The valve body is typically made from durable carbon steel, coated for corrosion protection, while the critical disc component is crafted from 316L stainless steel. This material choice provides enhanced resistance to pitting and crevice corrosion, especially in environments with chlorides.
- Superior Sealing: The PTFE (Teflon) seat ensures a bubble-tight seal with low torque operation. PTFE is known for its chemical inertness, a wide temperature tolerance, and excellent anti-stick properties, reducing wear and maintenance.
- Efficient Flow Design: The disc design minimizes pressure drop across the valve, promoting efficient flow and reducing energy costs for pumping systems.
- Versatile Operation: The valve is supplied with a manual lever or handwheel as standard. Options for gear operators or pneumatic/electric actuators are available to suit automated process control requirements.
- Broad Application Suitability: Ideal for use in water treatment, chemical processing, food and beverage, pharmaceutical, HVAC, and general industrial services where reliable isolation and regulation are needed.
To provide a clear overview, here are some of the primary technical specifications:
| Specification | Detail |
| Nominal Diameter (DN) | 150 (6") |
| Pressure Rating (PN) | 10 (10 bar) |
| Connection Standard | DIN 3202-F1 Wafer |
| Disc Material | AISI 316L Stainless Steel |
| Seat Material | PTFE (Virgin Grade) |
| Shaft Material | Stainless Steel (Standard) |
| Body Material | Carbon Steel (WCB), Epoxy Coated |
| Leakage Class | Class A (Zero Leakage) with PTFE seat |
| Operating Temperature | -20°C to +200°C (with PTFE seat) |
The advantages of choosing this valve extend beyond its specifications. For our clients, it translates into tangible benefits such as reduced downtime due to its reliable sealing, lower lifetime costs from its corrosion-resistant materials, and flexibility in system design due to its compact wafer form.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of a wafer-style connection?
A: Wafer-style valves are designed to be clamped between two pipe flanges using through-bolts. This makes them lighter, more compact, and often more cost-effective than lug-style or flanged-end valves, while still providing a secure connection.
Q2: Can this valve be used for throttling (flow control) or is it only for on/off service?
A: While butterfly valves are excellent for on/off isolation, this model, with its PTFE seat and disc design, is also suitable for moderate throttling applications. For precise control, pairing it with a modulating actuator is recommended.
Q3: Is the 316L stainless steel disc suitable for seawater or high-chloride applications?
A: AISI 316L offers better corrosion resistance than standard 304 stainless steel, particularly against chlorides. It is a good choice for many brackish water and mild chemical environments. For full seawater immersion, specific super duplex grades might be suggested; please consult with us for extreme conditions.
Q4: What types of actuators can be fitted to this valve?
A: The valve is prepared with a standardized shaft for easy attachment. We can provide or recommend compatible pneumatic (double-acting or spring-return), electric, or hydraulic actuators based on your control system needs.
Q5: What is the delivery lead time for this DN150 valve?
A: Standard models are typically available from stock or have a short production lead time. Exact delivery schedules depend on order quantity and specific configuration (like actuator type). We provide clear timelines upon inquiry.
Q6: Do you offer customization, such as different seat materials or special coatings?
A: Yes, customization is possible. Alternative seat materials like EPDM or Viton for different media, or special epoxy coatings for the body, can be arranged. Please provide your application details for a tailored solution.
Q7: What is included with the standard valve delivery?
A: The standard supply includes the valve with a manual lever/handwheel, necessary gaskets (where applicable), and identification tags. Actuators and mounting kits are quoted separately.
Q8: How does the PN10 pressure rating relate to other standards like ANSI Class?
A> PN10 is a metric pressure rating equivalent to approximately 10 bar (145 psi) at room temperature. It is roughly comparable to ANSI Class 150. Always consider the specific temperature-pressure curve for your application.
