Rubber Flap Check Valve

产品概览

The Rubber Flap Check Valve is a highly efficient, non-return valve designed for water, wastewater, and slurry applications. Featuring a flexible rubber flap, this valve ensures reliable sealing with minimal pressure drop, making it ideal for systems where low resistance and debris tolerance are critical.

Constructed from durable materials such as EPDM or NBR rubber and cast iron or stainless steel, this valve is resistant to corrosion and abrasion, ensuring long-term performance in demanding environments. Its simple yet robust design allows for easy installation and maintenance, making it a cost-effective solution for municipal, industrial, and irrigation systems.

主要功能

Flexible Rubber Flap:Made from EPDM or NBR rubber, ensuring tight sealing and resistance to wear.Self-cleaning design prevents clogging from debris, sludge, or fibrous materials.

低电阻设计Minimal pressure drop ensures efficient flow and reduces energy consumption.Ideal for low-pressure systems such as water supply and drainage networks.

Debris Tolerance:Wide-body design allows the valve to handle water with high solids content (e.g., sewage, industrial slurry).

Corrosion Resistance:Body materials: Ductile iron (epoxy-coated) or stainless steel (ASTM A351 CF8M).Suitable for corrosive media such as seawater and chemical-laden water.

Easy Installation & Maintenance:Compact and lightweight design simplifies installation in tight spaces.No external actuation required; operates purely on flow dynamics.

运行优势

Energy Efficiency: Low head loss (Kv value ≥ 0.8) reduces pump energy consumption.

Debris Resilience: Rubber flap design resists clogging from sand, grit, and fibrous materials.

Low Maintenance: No lubrication required; inspection via removable cover.

Cost-Effective: Simple design reduces initial and lifecycle costs.
