1. Wafer Type Design
Compact Face-to-Face Dimensions–The wafer design reduces overall length and weight, saving installation space and reducing pipeline load.
Simple & Fast Installation–The valve is sandwiched between standard flanges with just a few bolts, cutting installation time and labor costs significantly.
Cost-Effective for High-Volume Applications–With simpler construction and lower material consumption, the wafer valve offers excellent performance-to-cost ratio for general service applications.
2. Body Material–ASTM A126 Class B (Gray Iron)
Reliable Strength for Standard Pressures–ASTM A126 Class B gray iron delivers sufficient mechanical strength for PN16 and Class 150 general service applications.
Excellent Machinability & Dimensional Stability–The material allows precise casting and tight tolerances, ensuring reliable flange sealing and smooth operation.
Cost-Effective with Upgrade Options–This economical choice can be readily upgraded to ductile iron, WCB, stainless steel, or duplex alloys for more demanding conditions.
3. Disc Material–CF8 Stainless Steel (AISI 304)
Superior Corrosion Resistance for General Service–CF8 resists oxidation and corrosion in water, mild chemicals, and atmospheric exposure, ensuring a long service life.
Safe for Potable Water & Food Applications–The non-toxic material, combined with approved seats, meets WRAS and ACS standards for drinking water and food processing.
Strong Yet Lightweight–CF8 offers good mechanical strength while reducing overall valve weight, easing handling and installation.
4. Seat Material–NBR (Nitrile Rubber)
Excellent Oil & Fuel Resistance–NBR maintains elasticity and sealing integrity even after prolonged contact with mineral oils, greases, and hydrocarbons.
Good Abrasion & Tear Resistance–The seat withstands wear from small particles and frequent cycling, extending sealing life.
Broad Compatibility & Cost-Efficiency–With a -10℃ to +80℃ range, NBR delivers bubble-tight shut-off at a competitive cost, with EPDM, Viton, PTFE, or hard back-up seats available as alternatives.
5. Stem Material–SS420 (AISI 420)
High Tensile & Yield Strength–Hardened SS420 provides robust torque transmission, especially for large-diameter or high-pressure valves.
Excellent Wear & Galling Resistance–The hardened surface resists fretting wear, reducing maintenance needs over many cycles.
Blow-Out Proof with Corrosion Protection–The stem features a retention mechanism for safety, and can be supplied in SS304, SS316, or Monel K500 for harsher environments.
6. Actuator Options & ISO 5211 Mounting
Standardized Interface–The ISO 5211 top flange accepts actuators from any brand, enabling easy replacement without pipeline modifications.
Wide Range of Actuator Compatibility–Valves can be fitted with hand levers, gear operators, electric, pneumatic, hydraulic, or chain-wheel drives to suit any control requirement.
Custom Interface Available–Non-ISO mounting patterns and drive connections can be manufactured to match special actuator specifications.
