Direct-acting valves work well at low pressures or in small footprints, as they don’t require pilot pressure. Pilot‑operated valves, however, offer higher flow and pressure capacity, making them ideal for industrial, HVAC, or steam applications—while using smaller coils efficiently.

Yes—many models feature PTFE/EPDM seals, stainless or brass bodies rated up to 350 °F steam or 210 °F hot water. Explosion‑proof and slow‑close options also protect against extreme conditions like washdown environments or pressure spikes.

Inspect every 6–12 months under normal use. Clean strainers and lubricate if needed. More frequent service is advisable in harsh or dirty environments.

Most ASCO valves support universal mounting—horizontal, vertical, or inverted—but check model-specific instructions for exceptions or performance shifts.
