Danfoss inspection / service kit, code 027F3091, for the pilot-operated PM servo main valves type PMFL, PMFH, PM, PML, PMLX and MRV in size 80. The kit contains the valve cone and sealing parts required to inspect and overhaul the main valve, and covers both cone types used in that size. Supplied single pack (1 pc). PM main valves are the servo (pilot-operated) main valves of a Danfoss liquid-level or pressure-regulating station; this kit renews the wear parts without replacing the valve body. Match the kit to the main-valve size (80). Spare part / accessory — price on quote (login-gated on the Danfoss store).
