As a leading manufacturer with ISO9001 certification, Shanghai Zhibang Valve Manufacture Co., Ltd. specializes in providing robust and reliable fluid control solutions for demanding marine environments. Our GB/T3036-94 Marine Semi-Lug Hydraulic Butterfly Valve, crafted from durable cast steel, is engineered to deliver exceptional performance and longevity in critical hydraulic systems. With an annual export value reflecting our global reach and commitment to quality, we understand the precise needs of shipbuilders and marine engineers worldwide. This valve represents our dedication to combining stringent manufacturing standards with practical, high-performance design, ensuring your operations run smoothly and safely.
This valve is designed to meet the rigorous demands of marine applications, offering superior sealing, easy operation, and minimal maintenance. Its semi-lug design provides a secure, bolt-through connection that is ideal for system isolation, while the hydraulic actuation ensures precise and reliable flow control even under high-pressure conditions. The cast steel construction guarantees resistance to corrosion and mechanical stress, making it a dependable component for seawater cooling, ballast, bilge, and other essential shipboard systems.
Key Features & Technical Advantages:
- Rugged Construction: The valve body and disc are manufactured from high-grade cast steel, providing excellent strength and durability to withstand harsh marine conditions, including vibration and shock loads.
- Superior Sealing Performance: Features a resilient seat (options like EPDM or NBR available) that ensures bubble-tight shut-off, preventing leakage and ensuring system integrity.
- Efficient Hydraulic Actuation: Allows for remote and automated operation, enabling precise modulation of flow. This is crucial for modern, integrated vessel control systems.
- Semi-Lug Design Benefit: The lugged body allows for easy installation and removal from the pipeline without disturbing adjacent piping, simplifying maintenance and reducing downtime.
- Compliant Design: Manufactured in accordance with the GB/T3036-94 standard, ensuring dimensional interchangeability and performance reliability recognized in the industry.
- Corrosion Resistance: Surface treatments and coatings are available upon request to enhance corrosion resistance against seawater and other aggressive media.
- Bi-Directional Flow Capability: Designed to handle flow effectively in both directions, offering flexibility in system design and installation.

Frequently Asked Questions (FAQ):
-
What is the main advantage of a semi-lug design over a wafer or full-lug design?
The semi-lug design combines benefits. Unlike a wafer valve, it allows for downstream piping isolation and can be mounted using bolts through the lugs, providing a more secure connection. Compared to a full-lug valve, it is often more compact and cost-effective while still offering excellent service for many marine applications. -
Can this valve be used with fluids other than seawater/hydraulic oil?
Yes, the valve's compatibility depends primarily on the selected seat and seal materials. By specifying materials like EPDM, NBR, or Viton, the valve can be configured to handle a variety of media, including fresh water, oils, and certain chemicals. Please consult with our technical team for your specific media. -
What hydraulic pressure is required to operate the actuator?
The required hydraulic operating pressure varies based on valve size and the specific actuator model (double-acting or spring-return). Typical operating pressures range from 40 to 120 bar. Detailed actuator specifications and pressure requirements are available upon request. -
Is the valve suitable for high-vibration environments like engine rooms?
Absolutely. The cast steel construction and robust design provide inherent strength to withstand vibration. Furthermore, the secure semi-lug mounting and precision machining of components ensure the valve remains stable and leak-free in high-vibration areas. -
Do you provide custom coatings for enhanced corrosion protection?
Yes, we offer various surface treatments and coatings as an option. These can include epoxy coatings, galvanizing, or other specialized paints to provide an extra layer of defense against corrosive marine atmospheres and submerged service. -
What is the lead time for an order of these valves?
Lead times depend on the order quantity, size, and specific configuration (e.g., actuator type, seat material). For standard configurations, we maintain efficient production schedules. We recommend contacting our sales department with your project details for an accurate delivery estimate. -
Can the valve be supplied with manual override or position indicators?
Yes, these are common and valuable optional features. Hydraulic actuators can be equipped with manual override mechanisms for emergency operation. Visual or electronic position indicators can also be provided to show whether the valve is open, closed, or at an intermediate position. -
How does the GB/T3036-94 standard relate to other international standards like ISO or ANSI?
GB/T3036-94 is a Chinese national standard for butterfly valves that specifies dimensions, pressure ratings, and testing methods. It is widely recognized and accepted, particularly in Asian markets. Many of its specifications are aligned with common international practices, ensuring good compatibility. We can also manufacture valves to other standards based on customer requirements.
