Utility-side parts for chemical and process plants

A trap that blows through does not stop the plant, so it is not a fault — it is steam leaving quietly while three quotations come back. On shukchok valve, seal and fitting go into one basket, with nominal size and material at every position.

Your steam network

The maintenance window is fixed. Procurement is not.

Two weeks ahead you know what goes into the window: the trap that blows through, the seal that goes with it, the fitting that is due anyway once the line is open. What you do not know is whether all three arrive in time.

Three components usually means three suppliers, three queries about nominal size and material, and three minimum order values that turn a seal worth a few euros into the most expensive position of the day. And the part ordered last is still the one missing on Monday.

Sounds like a catalogue promise. That is why the nominal size is up front, before you sign in: job, component, size and material as a table at the position — and Miyawaki, Spirax Sarco, Caleffi, CEME, M&M and Pneumax sit in the same basket.

Four jobs, four components

Where a utility side actually fails

Each job has its own component in the catalogue, and each of them is regularly solved with the wrong one.

Remove condensate
A steam trap is not a valve on a timer. It tells steam from condensate and opens only for the latter — fail it open and you lose steam quietly, fail it shut and condensate backs up into water hammer. Neither raises an alarm.
Vent, but correctly
Steam and water circuits need different vents. The catalogue holds one explicitly for steam and two for water circuits; swapped, neither lasts a shift. That difference is in the specification table rather than in the answer to an enquiry.
Set pressure and relieve it
A steam pressure reducer at 1/2" and a corner safety valve at G 1/2" and 8 bar sit at opposite ends of the same question. One is sized on flow, the other on the worst case — mixing them up costs more than both together.
See and shut off
Sight glasses at 110 × 8, 217 × 6 and 280 × 10 mm, plus a safety ball valve with spring return in Rp 1/2 made of nickel-plated brass. That last detail is the one to check against your medium, and it therefore stands at the position.

What one basket changes

One process instead of three — and the price is there beforehand

shukchok is an open marketplace for industrial goods, so the trap comes from Miyawaki, the vent from Spirax Sarco, the solenoid valve from CEME. You put all three into the same basket and trigger one ordering process instead of three. Your purchase order number and your cost centre go in with them and stay with the order.

Anyone costing a repair compares first. Net prices stand there without a login, full-text search reaches the article number straight from a bill of materials, and a completed order goes back into the basket in one step — for the next window.

Across a customs border we deliver duty paid: duty and import charges are raised during the ordering process and are contained in the total, so the carrier does not re-bill you. Which delivery term applies to an article is stated on the article.

What the catalogue holds for it

Job, component, rating

Nominal size or set pressure is given where the article states it. Every row is a single line item, not part of a set.

Taken from the article data, 8 August 2026. Material numbers counted across all 114 records: 1.4404 on five articles, 1.4301 on three, 1.4571 on none; NBR on eight positions, FKM on six, PTFE on two, EPDM on one. Check the material at the position, not at the category.
Job	Component in the catalogue	Size / rating
Remove condensate	Steam trap Miyawaki SD1-2	—
Reduce steam pressure	Miyawaki RE1 pressure reducer	1/2"
Relieve overpressure	Corner safety valve	G 1/2", 8 bar
Vent a steam line	Spirax Sarco AV13 steam vent	1/2"
Vent a water circuit	Automatic vent / Caleffi VALCAL	1/4"
Shut off with spring return	Safety ball valve, nickel-plated brass	Rp 1/2
Prevent backflow	Check valve / swing check, brass	3/4" · 1 1/4"
Visual inspection	Sight glasses	110 × 8 · 217 × 6 · 280 × 10 mm

Two shelves — and how the second one grows here

A process plant buys from two shelves. Workshop and utility demand runs on nominal size, material and price — that is the shelf which is fully in the basket today. Documented demand runs on paperwork and a named contact: a PED category on the article, a TA-Luft leakage class, a tested stem packing to DIN EN ISO 15848-1, an inspection certificate 3.1 to EN 10204.

A single catalogue never carries both at once, and an open marketplace is built for exactly that. Whoever manufactures PTFE-lined valves, bellows-sealed valves, nickel-base alloys or materials such as 1.4571 does not have to build a shop for them. They list here, store their papers as article metadata and deliver through the same basket the maintenance team next door drops its seals into.

The range behind it

Categories with stock

Every count below comes from the live catalogue on 8 August 2026; the empty categories are linked from nowhere.

Two ways in

Put all three positions into one basket

Nominal size, material and price stand at every position, and several manufacturers go into one ordering process. And if you build valves yourself: shelf space here is free of charge.
