One Piece Stainless Steel Ball Valve – Reduced Port, 316, 1000 WOG, PT/NPT/PF, 1/4″–3″ (R-1B)

Описание продукта

A one piece stainless steel ball valve оцененный 1000 WOG, with the body cast as a single piece and welded closed. 316 (CF8M) is the stock material; 304 (CF8) is made to order. PTFE seats, manual quarter-turn lever, reduced port, −20 °C to +180 °C. Two end builds: самка × самка (F×F) от 1/4″ до 3″, и мужской × женский (M×F) размерами 1/4″, 3/8″ и 1/2″.

Because the body is one piece instead of two or three bolted or screwed sections, there is no body joint — one fewer place for the valve to leak. The trade-off is honest: it cannot be opened for service, and the bore is one pipe size smaller than the line. We say so plainly further down, and we point you at the valve you should buy instead.

Что на самом деле означает «1000 WOG»

WOG означает Вода, нефть, газ. Номинальная мощность 1000 WOG означает, что клапан рассчитан на Рабочее давление в холодном состоянии без ударных нагрузок — 1000 psi on those media.

Three things buyers get wrong about it:

• WOG — это показатель холодостойкости. It is not a steam rating. This valve runs from −20 °C to +180 °C, set by the PTFE seats — tell us your line temperature and we will confirm it suits.
• “Отсутствие ударов” входит в состав рейтинга. В трубопроводе при возникновении гидравлического удара или при резком запуске насоса наблюдаются скачки давления, значительно превышающие нормальное рабочее давление. Расчет следует производить с учетом величины скачка давления, а не показаний манометра.
• On this valve, “gas” means compressed air. Fuel gas lines (natural gas, propane) call for a gas-listed valve, and this is not one.

Если давление в вашей линии в холодном состоянии превышает 1000 psi, то дело не в клапане — сообщите нам значение давления, и мы подберем для вас подходящий вариант.

F×F или M×F — что вам нужно?

• Женщина × Женщина (Ж×Ж) — оба конца оснащены штекерными патрубками или фитингами. Это универсальный вариант, а также единственный, доступный в размерах от 1/2″ до 3″.
• Мужчина × Женщина (М×Ж) — one male end screws straight into a female port, so you save a fitting and shorten the assembly. Available in 1/4″, 3/8″ and 1/2″ only. If you need M×F above 1/2″, see the two-piece MxF ball valve (1/2″–2″, full port).

Dimensions for both builds are on the PDF dimension sheets at the top of this page.

Приложения

A reduced-port, non-serviceable body is a deliberate trade: the smallest envelope and the fewest joints of the three ball valve body types, at the lowest cost of the three. It belongs where those three things matter more than full flow or in-line repair.

• Instrument and gauge line isolation — the shut-off ahead of a pressure gauge or transmitter, so the instrument can be changed without draining the line. Open it slowly; this is an isolation valve, not a throttling one.
• OEM machinery and skid-mounted systems — small-bore utility shut-offs built into a machine frame or a packaged skid, where the valve is replaced as a unit rather than rebuilt in place.
• Установки в ограниченном пространстве — panels, cabinets and pipe runs where a two-piece or three-piece body will not fit. With no mid-body joint there is nothing to add length to the body.
• Compressed air branch isolation — take-offs from a plant air header to a machine, a filter-regulator or a blow-down point.
• Water and oil utility lines — general shut-off on cooling water, wash-down, lubrication and fuel-oil transfer lines up to 1000 psi cold.

Not for pump suction lines (use a full-port valve), fuel gas, steam, potable water or oxygen service — see the table above.

Часто задаваемые вопросы

What is a one piece stainless steel ball valve?

A ball valve whose body is cast as a single piece and welded closed, instead of being bolted or screwed together from two or three sections. There is no body joint, so there is one fewer place for a line to weep. The trade-off is that the valve cannot be opened for service and the port is reduced — the bore is one pipe size smaller than the line. If you want the same no-body-joint construction with a full-port bore, see the seal-welded two-piece ball valve (V-2B / V-2C).

Что означает «1000 WOG»?

WOG stands for Water, Oil, Gas. A 1000 WOG rating means the valve is rated for 1000 psi of cold, non-shock working pressure on those media. It is not a steam rating. On this valve “gas” means compressed air — it is not listed for fuel gas.

Каков диапазон рабочих температур?

−20 °C to +180 °C, set by the PTFE seats. Tell us your line temperature and we will confirm the valve suits it.

Какие размеры доступны?

Female × female (F×F) from 1/4″ to 3″ — 1/4″ to 2″ as standard, 2-1/2″ and 3″ on request. Male × female (M×F) in 1/4″, 3/8″ and 1/2″. Dimensions are on the two PDF dimension sheets at the top of this page.

Какие стандарты резьбы вы поставляете?

PT (коническая) — это стандартная резьба; NPT и PF также имеются в наличии.

316 or 304 — which should I order?

316 (CF8M) is the stock material and the one to choose wherever chlorides are present: brine, seawater, coastal air, most chemical service. The molybdenum in 316 is what resists chloride pitting. 304 (CF8) is made to order for general water, air and oil duty.

Можно ли открыть этот клапан для очистки или ремонта?

No. The body is welded, so it cannot be taken apart. That is the trade-off for having no threaded body joint to leak. If you need to service the valve in line, buy the трехсекционный шаровой кран instead. If you only need full-port flow and still want no threaded body joint, the seal-welded two-piece ball valve (V-2B / V-2C) is the one to look at.

Это клапан с полным проходом?

No. It is a reduced (standard) port valve — the bore is smaller than the pipe. If you need full bore flow, buy the seal-welded two-piece ball valve.

Можно ли установить на него привод?

No. This body has no actuator mounting pad. If you need automation, buy the one-piece pneumatic ball valve, which has the ISO 5211 pad cast into the body.

Можете ли вы предоставить сертификат на материал?

Да. Сертификат завода предоставляется по запросу.
