| S20 - COMPLETE LIST OF OPTIONS AND ACCESSORIES: | ||
| ............... | Closed center plug kit, for outlet sections with porting 2 in their model code. (Cannot be used with power beyond) | |
| 20-AGPB | ............... | Power beyond cartridge kit, for outlet sections with porting 2 in their model code. |
| 20-D | ............... | Three-position detent kit. |
| 20-D2 | ............... | Two-position detent kit, P to A and neutral. |
| 20-2D | ............... | Two-position detent kit, P to B and neutral. |
| 20-DS | ............... | Spool is detented in one work position (P to A), and springs to center (P to B) from the other. |
| 20-SD | ............... | Spool springs to center in one work position (P to A), and detented (P to B) in other position. |
| 20-K | ............... | Fourth position float kit, use on last spool section in assembly only. |
| 20-S | ............... | Spring to center kit. |
| 20-SWC | ............... | Spring to center kit with normally closed electric switch. |
| 20-SWO | ............... | Spring to center kit with normally open electric switch. |
| 20ASB | ............... | Series block allows the customer to meter multiple work sections independently without losing fluid to tank core. The down side to this section is that pressures are additive and pressure rating of valve is reduced to 3000 psi (207 bar) because the tank core is seeing system pressure. This section must be installed between two spool sections to put them in series. (0.656” [16.7mm] casting width) Note: Adjacent work section towards Inlet must have Series call out in model code. Joystick ("A" option) cannot be used when 20ASB is used between two adjacent work sections. |
| 20ASP | ............... | Series/Parallel block (also referred to as a tandem flow or priority valve) allows the customer to meter multiple work sections independently. The neutral flow path is in parallel but the pressure core is in series. Tank fluid is not combined to neutral flow passage. Upstream section has priority when shifting multiple sections. Pressures are not additive. The pressure rating remains at 4500 psi (301 bar) since the tank cores are not pressurized. This spool section must be installed between two spool sections to put them in series/parallel. (0.656" [16.7mm] casting width) Note: Joystick ("A" option) cannot be used when 20ASP is used between two adjacent work sections. |
| 20ASD | ............... | Series drain block, required for inlet relief to function correctly when using series block(s) (20ASB) in an assembly. (0.656" [16.7mm] casting width) |
| 20HA | ............... | Joystick handle kit for series 20, note, this kit may only be used on two adjacent spool sections in a valve assembly, and both of these two sections must have the (A) actuator call out in their model codes. |
| 20HB | ............... | B-style handle kit, with bent handle, use on spool sections with (B) handle call out. |
| 20HC | ............... | C-style handle kit, with straight handle, use on spool sections with (C) handle call out. |
| 20HB-K | ............... | Replacement handle kit which includes ball knob, bent handle and jam nut. |
| 20HC-K | ............... | Replacement handle kit which includes ball knob, straight handle, jam nut, linkage and cap screw. |
| 20TR_ | ............... | Tie rod kits, specify number of spool sections in valve assembly, i.e. 3 spool sections in valve assembly, requires using 20TR3 tie rod kit. Please note that when using extra items in the assembly, such as series blocks, drain blocks etc., the tie rod kit must have its length extended. |
| SEAL KITS | ||
| ............... | Replacement seal kit for work section. | |
| ............... | Seal kit, contains seals for use in between work sections. | |
| ............... | Replacement seal kit for inlet section. | |
| ............... | Replacement seal kit for outlet sections. | |
| Please feel free to contact the factory with your ideas regarding custom options or accessories, we will be happy to review them to see if they can be put into production for your assemblies. | ||
