PN16 Brass Horizontal Check Valve with Female Threaded Ends

Key Features

Product Specifications

Sizes Shown in the Current Product Images

Check Valve Function

A check valve is used to allow flow
in the intended direction while helping restrict
reverse flow through the pipeline.

The flow-direction arrow visible on the body
indicates the intended direction of fluid movement.
Installation should follow the specified flow direction.

Technical Buyer Notes

Confirm the Exact Thread Standard

The images clearly show female threaded ends,
but they do not identify the exact pipe-thread standard.

BSPP, BSPT, NPT or another standard
should therefore not be assumed from appearance alone.

Buyers should specify the required thread standard
directly in the RFQ.

For additional guidance, see our

BSP vs NPT thread guide
.

PN16 Does Not Define Every Product Parameter

The valve body is marked PN16.
However, PN16 does not by itself define
the thread standard, temperature range,
medium compatibility or internal mechanism.

These requirements should be confirmed independently
for the specific purchasing application.

Confirm Installation Orientation

The product is presented as a horizontal-style check valve,
but the allowable installation orientation
should still be confirmed for the final specification.

Do not assume that a check valve can be installed
in any orientation solely from its external appearance.

Confirm the Internal Mechanism

One of the product images provides a view
of the internal closing component.

However, the current images alone are not sufficient
to confirm whether the valve should be described
as spring-loaded, swing type or another specific mechanism.

The internal design should therefore be confirmed
before that terminology is included in a final specification.

Product Details

The product image set includes individual DN15,
DN25 and DN50 views, a complete size comparison,
threaded connection details and an internal component view.

For replacement or OEM projects,
these views can be used together with dimensions,
thread requirements and an existing sample
to improve product matching.
