As a leading manufacturer with a strong global footprint, Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our premium CB/T3591-2005 Ductile Iron Gate Valve with Blow-Proof Stem Design. Engineered for reliability in demanding industrial applications, this valve combines robust construction with advanced safety features to ensure leak-free operation and long service life under PN10 and PN16 pressure conditions. Our commitment to quality, backed by ISO9001 certification, guarantees that every valve meets stringent performance standards, providing you with a dependable solution for your fluid control systems.
Our gate valve is meticulously designed to offer superior performance and safety. The key features and technical advantages are detailed below:
- Blow-Proof Stem Design: The innovative stem design is a critical safety feature that prevents the stem from being ejected under high internal pressure, protecting personnel and equipment. This is achieved through a specialized locking mechanism integrated into the yoke and bonnet assembly.
- Premium Ductile Iron Body (QT400-18): The valve body is cast from high-grade ductile iron, offering excellent tensile strength, impact resistance, and pressure-bearing capacity, far superior to standard gray cast iron.
- Double Disc Parallel Seat: Features a parallel wedge gate design that provides a tight seal against both seats, minimizing leakage and ensuring smooth, low-torque operation from fully open to fully closed positions.
- Corrosion-Resistant Trim: Standard trim includes a stainless steel stem and optional stainless steel seat rings, providing enhanced resistance to corrosion, erosion, and galling, which extends the valve's operational lifespan.
- Versatile Pressure Ratings: Available in both PN10 (10 bar) and PN16 (16 bar) pressure classes, making it suitable for a wide range of medium-pressure applications in water supply, wastewater, oil, and gas pipelines.
- Full Bore Design: Provides minimal flow resistance and pressure drop when fully open, ensuring efficient system throughput and reducing pumping energy costs.
- Robust Flanged Ends: Standard flanged connections are manufactured to relevant dimensional standards (like GB, ANSI, DIN, JIS), ensuring easy and secure installation into existing piping networks.
- Multiple Actuation Options: Operated primarily by a handwheel, with the option for gearbox operation (bevel gear or worm gear) for valves with larger diameters or higher operating torques.

Frequently Asked Questions (FAQ)
-
What does "Blow-Proof Stem" mean and why is it important?
A blow-proof stem design incorporates mechanical features that physically prevent the stem from being forcibly ejected from the valve body if internal pressure acts against the closed gate. This is a crucial safety feature that protects operators from injury and prevents catastrophic system failure. -
What is the main difference between PN10 and PN16 pressure ratings?
PN10 indicates a nominal pressure rating of 10 bar, while PN16 is rated for 16 bar at ambient temperatures. The PN16 valve is constructed with slightly more robust dimensions to handle the higher pressure. Selection depends on your specific system's maximum working pressure. -
Can this valve be used for steam service?
Yes, it can handle saturated steam within its specified temperature range of up to 120°C. For higher temperature steam applications, material verification and specific seat/seat material selection should be discussed. -
What flange standards are available?
Standard valves are supplied with flanges machined to Chinese GB standards. Flanges to other common standards like ANSI, DIN, or JIS are available as a customization option upon request. -
Is the valve suitable for underground burial or corrosive environments?
The standard ductile iron body has good corrosion resistance but may require external epoxy coating or cathodic protection for direct burial. For highly corrosive fluids, please inquire about alternative trim materials like full stainless steel seats. -
Do you offer actuation options other than a handwheel?
Yes. For larger sizes or high-pressure applications where operating torque is high, we offer optional gear operators (bevel gear or worm gear). Electric or pneumatic actuators can also be sourced as a package. -
What is the lead time for an order?
Lead times vary based on order quantity, size, and any customizations. Standard sizes in PN10/PN16 are typically available from stock or have shorter production cycles. We provide accurate lead time estimates with every quotation. -
Does the valve come with a warranty?
Yes, our valves are covered by a standard warranty against defects in material and workmanship. The specific warranty period and terms are provided with our commercial offer.
