Product Description

Product Description

CHECK VALVE
 
A compact, self-actuated check valve that permits flow in the intended direction and closes automatically on reverse flow to prevent backflow and pump damage.
 
Designed for low pressure drop and reliable sealing, it is available with soft-seal and hard-seal options and in corrosion-resistant materials for different temperature and chemical environments.

Product Categories

Wafer Check Valve

A compact, lightweight check valve designed to fit between two flanges without requiring additional bolting. This space-saving design uses the flange bolts to secure the valve in place, making it ideal for applications with limited installation space. It automatically prevents backflow by allowing fluid to flow in one direction only.

Split Body Check Valve 

A two-piece or multi-piece check valve featuring a separable body design that allows for easy maintenance, inspection, and internal component replacement without removing the entire valve from the pipeline. This design is particularly advantageous for applications requiring regular servicing or where downtime must be minimized.

Vertical Check Valve

A check valve specifically designed for vertical pipeline installations where fluid flows upward. The valve mechanism is oriented to work optimally with vertical flow direction, ensuring reliable backflow prevention in vertical piping systems such as pump discharge lines and vertical risers.

Toilet Check Valve

A specialized check valve designed for toilet and sanitary applications to prevent wastewater backflow into the freshwater supply system. This valve provides essential protection against contamination and ensures compliance with plumbing codes and health regulations in residential and commercial bathroom installations.

Male-Female Threaded Check Valve

A check valve featuring both male (external) and female (internal) threaded connections, providing versatile installation options in threaded piping systems. This dual-thread design allows for flexible connection configurations and easy integration into existing plumbing or industrial piping networks.

Horizontal Check Valve

A check valve engineered for horizontal pipeline installations where fluid flows parallel to the ground. The internal mechanism is optimized for horizontal flow patterns, ensuring efficient operation, minimal pressure drop, and reliable backflow prevention in horizontal piping systems.

Stainless Steel Horizontal Check Valve

The Stainless Steel Horizontal Check Valve is a premium one-way flow control device designed for demanding industrial and commercial applications. Engineered with high-grade stainless steel construction, this valve ensures exceptional durability and corrosion resistance in harsh operating environments.

Brass Horizontal Check Valve

The Brass Horizontal Check Valve offers a cost-effective and reliable solution for preventing reverse flow in residential, commercial, and light industrial piping systems. Manufactured from high-quality brass alloy, this valve combines durability with excellent performance characteristics.

Detailed Pictures

AUTOMATIC UNIDIRECTIONAL CLOSURE
 
Uses the media's pressure to open and a reverse pressure differential to close, providing reliable one-way flow without external power or control.

LOW-PRESSURE DROP OPTIONS
 
Multiple internal geometries are available to minimize pressure loss across the valve, improving system efficiency and reducing pumping costs.

SEALING VARIANTS (SOFT / HARD)
 
Soft-seal options deliver low leakage and tight shutoff for potable systems; hard-seal constructions suit high temperature or abrasive media where durability is required.

SELECTABLE CRACK / OPERATING PRESSURE
 
Different designs produce different opening (cracking) and seating pressures, so the valve can be matched to pump curves and system requirements.
