PN25 PPR Stop Valve 20-40mm Chrome Plated with Anti-Slip Handle

Specification

Working Principle

1.Vertical Disc Movement

• Rotating the handle/actuator lowers or raises the valve stem.
• The disc (plug) attached to the stem moves perpendicular to the flow direction.

Open state: Disc lifts → fluid flows around it.

Closed state: Disc presses down → seals tightly against the seat ring.

2.Sealing Action

• Disc and seat create metal-to-metal (or soft-seated) contact.
• Force applied by the stem compresses the disc → blocks flow completely.

3.Flow Path Design

• Fluid enters → hits an internal baffle → changes direction twice (typically S-shaped path).
• Causes turbulence and pressure drop → enables flow control but reduces efficiency.

Features:

1.Versatile Sizing

Standard sizes: 20-40 mm

Custom dimensions available upon request.

2.Robust Pressure Rating

PN25 (25 bar pressure rating) for reliable performance in medium-pressure systems.

3.Hybrid Material Construction

PPR Base: Corrosion-resistant, lightweight, and ideal for chemical/water applications.

Brass Valve Core: Ensures precise sealing and mechanical durability.

Chrome-Plated Exterior: Enhanced aesthetics and surface protection.

4.Global Compliance

Conforms to ISO/DIN international standards for quality and safety.

5.Customization Options

Colors, sizes, and other specifications can be tailored to project needs.

Applications

1.Flow Regulation

Throttling Control: Precisely adjust flow/pressure (e.g., HVAC balancing, pressure reduction stations).

Process Optimization: Manage fluid rates in industrial processes (chemical dosing, boiler feedwater).

2.High-Pressure/Temperature Services

Steam Pipelines: Reliable shutoff in boilers, steam traps, and distribution headers (PN25+ rating).

Hot Oil/Gas Systems: Brass/PPR construction resists corrosion in thermal fluid circuits.

3.Corrosive/Sanitary Environments

Chemical Transport: PPR body withstands acids/alkalis; chrome plating adds protection.

Potable Water: Compliant for drinking water systems (smooth PPR surface prevents contamination).
