Optional Seat Selections
| Material | Operating Temperature | Operating Pressure | Description |
|---|---|---|---|
| PTFE | -112 ~ 248°F | 150 lb | Fluorocarbon-based polymer—lowest operational torque due to low coefficient of friction |
| RPTFE | -80 ~ 120°C | 150-600 lb | Reinforced PTFE—enhanced strength, stability, and wear resistance |
| PCTFE | -112 ~ 248°F / -190 ~ 120°C | 150-300 lb | Thermoplastic chlorofluoropolymer—dimensionally stable, rigid, resistant to cold flow, very low gas permeation |
| Nylon | -31 ~ 248°F / -45 ~ 250°C | 150-300 lb | Ideal for high-pressure air, oil, and gas media—not suitable for strong oxidizing agents |
| Molon | -49 ~ 482°F | 150-300 lb | Modified Nylon (Nylon + MoS₂)—similar to nylon but with higher operating temperature |
| Devlon | -29 ~ 80°C | 150-1500 lb | Polyamide with additives—wide application range, excellent wear, low friction, improved impact strength |
| PEEK | -20 ~ 176°F | 150-1500 lb | High-performance engineered thermoplastic—excellent water/chemical resistance, unaffected by hot water/steam |
| Metal | -29 ~ 130°C / -20 ~ 266°F | 150-1500 lb | Used for high temperature, wear resistance, impact resistance, granular media conditions |
| – | -50 ~ 150°C / -58 ~ 302°F | 150-2500 lb | – |
| – | -100 ~ 260°C / -148 ~ 500°F | 150-2500 lb | – |
| As Request | – | 150-2500 lb | Custom seat materials available on request |
Optional Seal Selections
| Material | Operating Temperature | Operating Pressure | Description |
|---|---|---|---|
| EPDM | -46 ~ 150°C / -50 ~ 302°F | 150-600 lb | Synthetic rubber—excellent chemical resistance to acids and alkalis; not suitable for petroleum |
| NBR | -40 ~ 80°C | 150-2500 lb | Resistant to mineral oil-based lubricants, greases, hydraulic fluids, hydrocarbons, and water |
| HNBR | -40 ~ 80°C / -40 ~ 176°F | 150-2500 lb | Similar media stability to NBR with significantly better heat and oxidation stability |
| HNBR AED | -40 ~ 80°C / -40 ~ 176°F | 150-2500 lb | Typically used in high-pressure oil and gas applications |
| VITON | -40 ~ 176°F | 600-2500 lb | Fluorocarbon elastomer—compatible with a broad range of chemicals, excellent resistance to aggressive fuels |
| FVMQ | -29 ~ 200°C / -20 ~ 392°F | 150-2500 lb | Silicone polymer—far more resistant to oils and fuels than standard silicones |
