GRS2250 Series Dual-Function Globe Filter

Size Range: DN15～DN50

Temperature Range: -20℃～220℃
Pressure Rating: DIN PN1.6MPa to PN2.5MPa; ANSI 150LB
Connection Standards: BS, ISO, NPT, DIN, ANSI, BSPP, BSPT
Body Materials: Stainless Steel, Bronze
Filter Screen Material: 304 Stainless Steel
Disc Materials: 304 Stainless Steel, Bronze, PTFE
O-Ring Material: Siliconized Resin

Features and Benefits

The disc is made of PTFE, offering excellent sealing performance, easy replacement, and a service life comparable to the pipeline.

The filter adopts a new concave dual-filtration design, effectively preventing backflow of impurities, with no restrictions on installation position.

The stainless steel filter screen area is three times the inlet diameter, resulting in low flow resistance and excellent corrosion resistance.

The new siliconized resin O-ring offers good wear and high-temperature resistance. DN15 to DN25 sizes can be easily disassembled without special tools, and different materials can be selected based on the medium.

BNG4500 Series Pump Multi-Function Valve

Product Overview
Applicable Media: Water, oil, or other non-corrosive liquids
Operating Temperature: ≤80℃
Size Range: DN40～DN500
Pressure Rating: PN1.0～4.0MPa
Connection Standards: GB, ANSI, DIN, ISO, BS

Features and Benefits
Multi-Function Integration: Combines five functions—shut-off valve, silent check valve, balancing valve, anti-freeze and vacuum prevention, and signal detection—into one unit to meet various operational requirements.

Easy Installation: Detachable valve seat end and bottom connection design simplify installation and pipeline interfacing.

Anti-Freeze and Vacuum Prevention: Built-in bypass valve facilitates main channel drainage, effectively preventing freeze damage and vacuum negative pressure at the pump outlet.

Flow Regulation: External thread connection allows for precise flow adjustment.

LGR4450 Series Angle-Type Filter

Product Overview
Applicable Media: Water, air, steam (optional), oil, or other liquids

Operating Temperature: ≤80°C
Size Range: DN50～DN400
Pressure Rating: DIN PN1.0MPa～PN4.0MPa; ANSI 125LB～300LB
Connection Standards: GB, ANSI, DIN, ISO, BS
Body Materials: Cast iron, cast steel
Bonnet Materials: Cast iron, cast steel
Filter Screen Material: 304 stainless steel
O-Ring Materials: EPDM, NBR, PTFE, or siliconized resin

Features and Benefits

Internal special guide device at the valve outlet stabilizes flow and provides effective pump protection.

Widened filter opening design significantly reduces head loss, with near-zero flow resistance and easy maintenance.

Equipped with double-layer filter screen; after pipeline cleaning, the outer filter can be removed for continued use, extending service life.

Installation height can be adjusted as needed; main drainage devices and measuring instruments can be installed horizontally or vertically.

Widened pump flange space design facilitates bolt riveting, improving installation efficiency.
