The butterfly valves PD-series from Ghibson are soft seated butterfly valves. The PD-Series is designed for low pressure applications (max. 6/10 bar). They are produced in a variety of materials and are available with both wafer and lug bodies.
Key Features:
Soft-seated design
Wide range of available materials
Can be used in abrasive application
Suitable for pressures up to (6)10 bar, depending on the chosen material
Benefits of the PD series butterfly valves for low pressure
These valves are specifically designed for low-pressure applications, with a maximum pressure range of 6-10 bar, depending on the material of the "body seat". The choice of material is determined by the application's requirements and the process temperature.
These valves accurately control the flow of liquids or gases within maritime systems. They find common usage in fuel systems, lubrication systems, cooling systems, and other fluid handling systems aboard ships, offshore platforms, and various maritime vessels.
PD stands for PowDers, with mean that they also are usefull for handling abrasive bulk materials. Equipped with rubber seats, these valves feature a carefully crafted disc geometry that allows for effortless low-torque opening and closing, while significantly reducing seat wear over time. This provides extended lifespan and the possibility of using smaller actuators, resulting in economic and space-saving advantages.
Replaceable Soft Body Seat
The body seat is replaceable for sizes up to DN600 (Note: this size is vulcanized and therefore not replaceable). This feature extends the product's lifespan and maintains optimal performance. Consequently, the valve becomes economically advantageous in the long term, as replacing a single component can prevent costly repairs or the need to replace the entire unit.
Moreover, the PD valve is designed with a soft-seated feature, ensuring a tight seal and preventing leaks. This aspect is of utmost importance in maritime applications where leaks can result in safety hazards, environmental contamination, and expensive damage to equipment and systems.
Is the butterfly valve PD Series approved by any international safety standards?
Yes, the butterfly valve PD Series holds approval from several international safety standards.
The PD Series butterfly valve has undergone rigorous testing and meets the requirements of various international safety standards. It is approved by organizations such as the International Maritime Organization (IMO), American Bureau of Shipping (ABS), Det Norske Veritas Germanischer Lloyd (DNV GL), and Bureau Veritas (BV). These approvals ensure that the valve meets the highest standards of safety and reliability for use in maritime applications. For further information, please do not hesitate to contact us.
