Daikin-made PFA full-lined pure PTFE retaining ring Excellent corrosion resistance with a lining thickness of over 3mm Satisfactory for high purity as well

• Drainage and ventilation equipment

Daikin PFA full-lined pure PTFE balls, high boron silicon glass. Excellent corrosion and chemical resistance with a lining thickness of over 3 mm. Satisfactory for high purity as well.

• Drainage and ventilation equipment

1. The lining material is fully fluorinated F46, which has excellent corrosion resistance and can completely isolate the fluid from the drive components. 2. The runner is smooth and has low resistance, allowing for a greater flow rate to be achieved. 3. The diaphragm material is highly elastic, has excellent sealing properties, and can be easily opened and closed. 4. There is a marking indicating the opening and closing of the valve at the upper end of the valve cover.

• Drainage and ventilation equipment

1. Excellent chemical stability 2. Can be mounted horizontally or vertically 3. Low torque and can be used for long periods 4. Minimal physical friction and excellent sealing properties 5. Prevents dirt, static electricity, and liquid adhesion 6. The lining uses thick Teflon, which is highly resistant to corrosion 7. The mechanical sealing surface ensures zero leakage of liquids at flange joints, making it ideal for strong corrosive fluids such as hydrochloric acid, sulfuric acid, nitric acid, organic acids, strong oxidizers, alternating concentrated and diluted acids, and alkali alternation.

• Drainage and ventilation equipment

1. The lining material of the valve is PFA or FEP, with a thickness of 3 millimeters or more, and has high permeability resistance. 2. The material of the valve body can be selected according to the customer's preferences. 3. Permanent sealing method with flange joints. Applicable even with frequent thermal cycling. 4. The ball and valve seat fit perfectly, resulting in a high CV value. 5. The reinforced PTFE valve seat provides the ball with permanent cushioning power, ensuring sealing performance. 6. Anti-static. 7. The ball and stem are designed as a single unit to avoid potential failure situations, providing excellent fluid control capability.

High corrosion resistance and durability The high corrosion resistance unique to Teflon (PTFE/PFA) and its properties that prevent fluid adhesion make it ideal for fluids such as strong acids, gases, and food. Additionally, its unique internal structure prevents fluid retention, ensuring even greater durability and cleanliness. Adoption of a new valve body seal structure A backup rubber is attached to the valve body. The compression reaction force of the rubber presses the outer edge of the valve body against the body seal. Furthermore, to enhance airtightness, the center of the body seal is subtly raised inward. By fitting the valve body snugly, the sealing capability is completely ensured. High heat and pressure resistance to withstand harsh environments Even under conditions of 150°C and 1.0 MPa, the sealing capability and operability remain unchanged. With high heat resistance, pressure resistance, and durability, it can handle harsh environments. Triple seal structure to prevent liquid leakage The primary seal compresses the body seal onto the valve body. The secondary seal is provided by an O-ring. The tertiary seal is achieved through a tapered push on the valve rod. This triple seal structure completely shuts out leakage to the outside of the piping.
