The Atos HM-015/350-40 is a modular pressure relief valve for ISO 4401 size 06 sandwich stacks. HM valves are double-stage pressure relief valves with a balanced poppet. Type: Modular pressure relief valve.
HM — Atos double-stage modular relief valve, size 06, max flow 60 l/min.
015 — hydraulic configuration: double relief on ports A and B, with the relieved pressure cross-discharged.
350 — pressure range 5–350 bar.
40 — series number.
No seal suffix — NBR seals (standard execution).
Valve Size: 06. Max Flow: 60 l/min. Pressure Range: 5–350 bar. Max Pressure: 350 bar. Pressure Adjustment: Screw protected by cap, with locking nut; clockwise rotation increases the pressure.
Seals: NBR. Recommended Fluid Temperature (NBR): –20 °C to +60 °C. Ambient Temperature (standard execution): –30 °C to +70 °C. Hydraulic Fluids (NBR): mineral oils HL, HLP, HLPD, HVLP, HVLPD (DIN 51524) and HFC water-based fluids. Recommended Viscosity: 15–100 mm²/s. Fluid Contamination Class: ISO 4406 21/19/16, NAS 1638 class 10. MTTFd (EN ISO 13849): 150 years.
Mounting Surface: ISO 4401-03-02-0-05 (size 06). Port Diameter (A, B, P, T): 7.5 mm. Seals: 4 OR 108. Fastening Bolts: 4 socket head screws M5, length set by the modular stack. Assembly Position: Any position.
Sibling configurations in the same HM range: HM-011 (single on P), HM-012 (double on A and B, discharge to T), HM-013 (single on A), HM-014 (single on B). The KM range is the size 10 equivalent.
Frequently asked questions
What is the Atos HM-015/350-40?
The Atos HM-015/350-40 is a double-stage modular pressure relief valve for ISO 4401 size 06 stacks. It relieves ports A and B with cross-discharge, adjustable from 5 to 350 bar.
What does the 015 configuration mean?
015 is double relief on ports A and B, with the relieved pressure cross-discharged to the opposite port. HM-012 is the version that discharges to T.
What is the maximum flow?
The HM valve is rated for a maximum flow of 60 l/min at pressures up to 350 bar.
