FRUSSONIA Irrigation Valve Diaphragm Replacement Kit — 6-Pack for Rain Bird CP/CPF/DV/DVF/DAS/ASVF, Buna‑N + Screens & Screws

FRUSSONIA's 6-pack diaphragm replacement kit restores Rain Bird CP, CPF, DV, DVF, DAS and ASVF valves quickly by swapping worn diaphragms and essential small parts.

When an irrigation valve starts leaking, stalls or loses pressure, the problem is often a tired diaphragm or clogged small parts. This FRUSSONIA kit supplies six reinforced Buna-N rubber diaphragms plus matching filter discs, solenoid screens, screws and spare springs so you can perform a full-service valve refresh without hunting down individual components. The parts are sized to fit common Rain Bird valve families and built to tolerate outdoor exposure.

How will this kit fix my leaking or non‑sealing Rain Bird valve?

Replacing a hardened or torn diaphragm restores the valve's internal seal so the diaphragm can flex correctly under pressure. The included filter discs and solenoid screens remove debris that otherwise interferes with seating and flow. Together, these parts address the most frequent causes of valve failures in the supported Rain Bird models.

• Six reinforced Buna-N diaphragms sized for CP, CPF, DV, DVF, DAS, ASVF valves
• Filter discs and solenoid screens to stop particulate from blocking operation
• 36 corrosion-resistant stainless screws and extra springs for complete reassembly
• Designed to re-seal quickly and restore normal valve motion

Is installation difficult—what tools and time are required?

Installation is straightforward and intended for DIY service: a standard screwdriver and a few minutes per valve are usually all that's needed. Color-matched components make it easier to orient parts during reassembly, and the kit contains every small fastener you need so there’s no need to source extras mid‑job.

• Basic tools: flathead or Phillips screwdriver
• Estimated time: under 10 minutes per valve for most users
• All necessary screws, springs and seals included for a single valve service
• Clear fitment for listed Rain Bird series reduces guesswork

What materials are used, and how do they stand up to outdoor conditions?

The diaphragms are molded from Buna‑N (nitrile) rubber, chosen for resistance to abrasion, many irrigation chemicals and moderate UV exposure. Stainless fasteners resist corrosion, while screens and discs are engineered to prevent debris-related wear. These material choices aim to extend service intervals compared with generic replacement parts.

• Buna‑N rubber diaphragms for chemical and wear resistance
• Stainless steel screws reduce rust and maintain clamping force
• Solenoid screens and filter discs protect internal components from grit
• Components sized for typical system pressures used with Rain Bird valves

Which Rain Bird models will this kit fit and replace?

The kit is engineered to match the diaphragm geometry and small parts used in Rain Bird CP and CPF series plus DV, DVF, DAS and ASVF valve families. That compatibility covers many common residential and commercial valves, making the kit a convenient multi‑valve spare pack for homeowners and landscape pros.

• Compatible with Rain Bird CP and CPF valve series
• Fits DV and DVF valve models commonly found in irrigation systems
• Includes parts sized for DAS and ASVF valve variants
• Intended as a direct replacement where Rain Bird part dimensions match

Who is this for? Landscapers, irrigation technicians and homeowners managing sprinklers who want an affordable, complete parts set to revive multiple Rain Bird valves will find this kit useful. It’s aimed at people who prefer to troubleshoot and repair valves on their schedule, avoid downtime, and carry a compact stock of compatible parts for routine maintenance.
