Threaded S-Globe Valve — Product Features

“A manual threaded globe valve offering threaded connection options, a range of material choices and PTFE seals. Please refer to the accompanying technical specifications for further details.

Globe valve body

A threaded globe valve designed for manual on/off operation in pipework systems.

Manual globe valve operation

– Turn the handwheel anti-clockwise → the valve stem moves downwards, the disc closes, and the valve shuts off – Turn the handwheel clockwise → the valve stem moves upwards, the disc lifts, and the flow path opens

Connection type

Threaded connection; please confirm the required sizes and specifications.

Threaded connections

BSPT, BSPP and NPT thread types are available; please confirm the required dimensions and specifications.

Materials and seat options

The parts list includes WCB / CF8 / CF8M / 2205 body materials and PTFE seat assemblies.”

OPERATING PRINCIPLE

How Threaded S-Globe Valve Works

Manual threaded globe valves are a type of **positive-seal valve**, which rely on the interaction of the handwheel, valve stem and disc to control flow and regulate flow rate.

  1. Operation 1

    1. When the handwheel is turned, the trapezoidal thread on the valve stem converts the rotational movement of the handwheel into **up-and-down linear motion**, causing the disc to move up and down accordingly.

  2. 2. **Rotate the handwheel anti-clockwise**

    the valve stem is lifted upwards, causing the disc to move away from the seat sealing surface, thereby opening the medium passage; the flow rate of the medium can be adjusted by controlling the height to which the disc is raised.

  3. 3. **Rotate the handwheel clockwise**

    the valve stem is pushed downwards, forcing the disc tightly against the seat sealing surface, cutting off the flow of the medium and achieving a seal.

  4. > Key features

    The medium flows **unidirectionally**, entering from below the valve disc and exiting from above; the valve body is cast with a flow direction arrow, and **reverse installation is strictly prohibited**.

  5. Operation 5

    > As the medium must take a bend whilst flowing through the valve body, the pressure loss is greater than that of ball valves and gate valves.

Frequently Asked Questions

Find answers to common questions about sizing, materials, threaded connections and operating conditions.

What is S-type threaded globe valve?

S-type threaded globe valve is a forced-sealing manual globe valve with S-shaped internal flow path and female threaded ends. It can be used for pipeline shut-off as well as flow and pressure regulation. It is unidirectional and must be installed following the flow arrow on valve body.

What is the working principle?

The trapezoidal thread on the stem converts handwheel rotary motion into vertical movement of the disc. Counter-clockwise rotation lifts the disc to open and regulate flow; clockwise rotation pushes the disc tightly against the seat to shut off the medium. The S-shaped passage makes fluid flow smoother.

What is the operation method?

Manual multi-turn handwheel operation. Counter-clockwise to open, clockwise to close. It is not quarter-turn like ball valve.

What are the main product features?

Forced sealing, reliable shut-off. Able to throttle and regulate flow. Unidirectional flow, install according to flow arrow. Bent flow path leads to higher pressure drop. Compact threaded connection for easy installation.

Material options?

Standard SS304. Body, disc and stem are stainless steel. Seat:metal hard seal.

Do you do 100% pressure test?

Yes. Every valve will pass air leakage test before packing.

MOQ?

Small MOQ available. Mixed sizes in one order acceptable.

Packing method?

Each valve in plastic bag, then small box, carton outside. Wooden pallet optional.

Can I put my own logo /custom label?

Yes, OEM & ODM available. Logo on handle or body.

Can we use it for flow regulation?

Yes. Globe valve is specially designed for throttling and pressure control.

What’s the warranty?

12 months warranty against manufacturing defect. Not cover damage from wrong operation.

Pressure rating?

PN16 / 200WOG

How to prevent leakage?

Do not over-tighten thread when installation; avoid impact. Regular inspection for long time service.

“What sizes are available?

The general product specifications list sizes from 1/2” to 2” (DN15–DN50). The accompanying size chart currently covers DN15–DN50; please verify the specific dimensions for the size you require.

What materials can I choose from?

The original bill of materials includes 201, CF8, and CF8M valve body option

What are the temperature and pressure limits?

The accompanying general data indicates an operating pressure of 1.6 MPa and an operating temperature range of 0°C to 120°C. Suitability of this product for specific fluids and temperatures must be confirmed separately.

Can this valve be used for throttling?

The accompanying operating instructions recommend against leaving the valve in a partially open position for extended periods, as high-velocity fluid may erode the seat.

What is the lead time for orders?

We maintain a stock of 5,000 BSPT valves for standard orders; other thread types require customization, with a production capacity of 50,000 units within 15 days.

What is the product quality like? Is there a warranty period?

Every valve undergoes rigorous quality inspection, including testing of the material, threads, seals, and valve body, and is backed by a one-year warranty within the normal operating range of the medium.

Threaded S-Globe valve

“A manual threaded globe valve is a manually operated valve. The manual threaded globe valve (J11W) is a **positive-seal globe and control valve**, featuring BSPP/NPT internal threads at both ends. The valve stem drives the disc up and down, causing the disc to engage with or disengage from the seat sealing surface, thereby controlling the flow of the medium and regulating the flow rate.
